31 | // Copied from pve wiki: Revision as of 16:10, 27 October 2015 | |
32 | ||
33 | {pve} supports multiple authentication sources, for example Linux PAM, | |
34 | an integrated Proxmox VE authentication server, LDAP, Microsoft Active | |
35 | Directory and OpenID Connect. | |
36 | ||
37 | By using role-based user and permission management for all objects (VMs, | |
38 | Storage, nodes, etc.), granular access can be defined. | |
39 | ||
40 | ||
41 | [[pveum_users]] | |
42 | Users | |
43 | ----- | |
44 | ||
45 | {pve} stores user attributes in `/etc/pve/user.cfg`. | |
46 | Passwords are not stored here; users are instead associated with the | |
47 | <<pveum_authentication_realms,authentication realms>> described below. | |
48 | Therefore, a user is often internally identified by their username and | |
49 | realm in the form `<userid>@<realm>`. | |
50 | ||
51 | Each user entry in this file contains the following information: | |
52 | ||
53 | * First name | |
54 | * Last name | |
55 | * E-mail address | |
56 | * Group memberships | |
57 | * An optional expiration date | |
58 | * A comment or note about this user | |
59 | * Whether this user is enabled or disabled | |
60 | * Optional two-factor authentication keys | |
61 | ||
62 | CAUTION: When you disable or delete a user, or if the expiry date set is | |
63 | in the past, this user will not be able to log in to new sessions or start new | |
64 | tasks. All tasks which have already been started by this user (for example, | |
65 | terminal sessions) will **not** be terminated automatically by any such event. | |
66 | ||
67 | ||
68 | System administrator | |
69 | ~~~~~~~~~~~~~~~~~~~~ | |
70 | ||
71 | The system's root user can always log in via the Linux PAM realm and is an | |
72 | unconfined administrator. This user cannot be deleted, but attributes can | |
73 | still be changed. System mails will be sent to the email address | |
74 | assigned to this user. | |
75 | ||
76 | ||
77 | [[pveum_groups]] | |
78 | Groups | |
79 | ------ | |
80 | ||
81 | Each user can be a member of several groups. Groups are the preferred | |
82 | way to organize access permissions. You should always grant permissions | |
83 | to groups instead of individual users. That way you will get a | |
84 | much more maintainable access control list. | |
85 | ||
86 | [[pveum_tokens]] | |
87 | API Tokens | |
88 | ---------- | |
89 | ||
90 | API tokens allow stateless access to most parts of the REST API from another | |
91 | system, software or API client. Tokens can be generated for individual users | |
92 | and can be given separate permissions and expiration dates to limit the scope | |
93 | and duration of the access. Should the API token get compromised, it can be | |
94 | revoked without disabling the user itself. | |
95 | ||
96 | API tokens come in two basic types: | |
97 | ||
98 | * Separated privileges: The token needs to be given explicit access with ACLs. | |
99 | Its effective permissions are calculated by intersecting user and token | |
100 | permissions. | |
101 | * Full privileges: The token's permissions are identical to that of the | |
102 | associated user. | |
103 | ||
104 | CAUTION: The token value is only displayed/returned once when the token is | |
105 | generated. It cannot be retrieved again over the API at a later time! | |
106 | ||
107 | To use an API token, set the HTTP header 'Authorization' to the displayed value | |
108 | of the form `PVEAPIToken=USER@REALM!TOKENID=UUID` when making API requests, or | |
109 | refer to your API client's documentation. | |
110 | ||

112 | Resource Pools | |
113 | -------------- | |
114 | ||
115 | [thumbnail="screenshot/gui-datacenter-pool-window.png"] | |
116 | ||
117 | A resource pool is a set of virtual machines, containers, and storage | |
118 | devices. It is useful for permission handling in cases where certain users | |
119 | should have controlled access to a specific set of resources, as it allows for a | |
120 | single permission to be applied to a set of elements, rather than having to | |
121 | manage this on a per-resource basis. Resource pools are often used in tandem | |
122 | with groups, so that the members of a group have permissions on a set of | |
123 | machines and storage. | |
124 | ||
125 | [[pveum_authentication_realms]] | |
126 | Authentication Realms | |
127 | --------------------- | |
128 | ||
129 | As {pve} users are just counterparts for users existing on some external | |
130 | realm, the realms have to be configured in `/etc/pve/domains.cfg`. | |
131 | The following realms (authentication methods) are available: | |
132 | ||
133 | Linux PAM Standard Authentication:: | |
134 | ||
135 | Linux PAM is a framework for system-wide user authentication. These users are | |
136 | created on the host system with commands such as `adduser`. If PAM users exist | |
137 | on the {pve} host system, corresponding entries can be added to {pve}, to allow | |
138 | these users to log in via their system username and password. | |
139 | ||
140 | {pve} Authentication Server:: | |
141 | ||
142 | This is a Unix-like password store, which stores hashed passwords in | |
143 | `/etc/pve/priv/shadow.cfg`. Passwords are hashed using the SHA-256 hashing | |
144 | algorithm. This is the most convenient realm for small-scale (or even | |
145 | mid-scale) installations, where users do not need access to anything outside of | |
146 | {pve}. In this case, users are fully managed by {pve} and are able to change | |
147 | their own passwords via the GUI. | |
148 | ||
149 | LDAP:: | |
150 | ||
151 | LDAP (Lightweight Directory Access Protocol) is an open, cross-platform protocol | |
152 | for authentication using directory services. OpenLDAP is a popular open-source | |
153 | implementations of the LDAP protocol. | |
154 | ||
155 | Microsoft Active Directory (AD):: | |
156 | ||
157 | Microsoft Active Directory (AD) is a directory service for Windows domain | |
158 | networks and is supported as an authentication realm for {pve}. It supports LDAP | |
159 | as an authentication protocol. | |
160 | ||
161 | OpenID Connect:: | |
162 | ||
163 | OpenID Connect is implemented as an identity layer on top of the OATH 2.0 | |
164 | protocol. It allows clients to verify the identity of the user, based on | |
165 | authentication performed by an external authorization server. | |
166 | ||
167 | Linux PAM Standard Authentication | |
168 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
169 | ||
170 | As Linux PAM corresponds to host system users, a system user must exist on each | |
171 | node which the user is allowed to log in on. The user authenticates with their | |
172 | usual system password. This realm is added by default and can't be removed. In | |
173 | terms of configurability, an administrator can choose to require two-factor | |
174 | authentication with logins from the realm and to set the realm as the default | |
175 | authentication realm. | |
176 | ||
177 | ||
178 | {pve} Authentication Server | |
179 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
180 | ||
181 | The {pve} authentication server realm is a simple Unix-like password store. | |
182 | The realm is created by default, and as with Linux PAM, the only configuration | |
183 | items available are the ability to require two-factor authentication for users | |
184 | of the realm, and to set it as the default realm for login. | |
185 | ||
186 | Unlike the other {pve} realm types, users are created and authenticated entirely | |
187 | through {pve}, rather than authenticating against another system. Hence, you are | |
188 | required to set a password for this type of user upon creation. | |
189 | ||
190 | ||
191 | LDAP | |
192 | ~~~~ | |
193 | ||
194 | You can also use an external LDAP server for user authentication (for examle, | |
195 | OpenLDAP). In this realm type, users are searched under a 'Base Domain Name' | |
196 | (`base_dn`), using the username attribute specified in the 'User Attribute Name' | |
197 | (`user_attr`) field. | |
198 | ||
199 | A server and optional fallback server can be configured, and the connection can | |
200 | be encrypted via SSL. Furthermore, filters can be configured for directories and | |
201 | groups. Filters allow you to further limit the scope of the realm. | |
202 | ||
203 | For instance, if a user is represented via the following LDIF dataset: | |
204 | ||
205 | ---- | |
206 | # user1 of People at ldap-test.com | |
207 | dn: uid=user1,ou=People,dc=ldap-test,dc=com | |
208 | objectClass: top | |
209 | objectClass: person | |
210 | objectClass: organizationalPerson | |
211 | objectClass: inetOrgPerson | |
212 | uid: user1 | |
213 | cn: Test User 1 | |
214 | sn: Testers | |
215 | description: This is the first test user. | |
216 | ---- | |
217 | ||
218 | The 'Base Domain Name' would be `ou=People,dc=ldap-test,dc=com` and the user | |
219 | attribute would be `uid`. | |
220 | ||
221 | If {pve} needs to authenticate (bind) to the LDAP server before being | |
222 | able to query and authenticate users, a bind domain name can be | |
223 | configured via the `bind_dn` property in `/etc/pve/domains.cfg`. Its | |
224 | password then has to be stored in `/etc/pve/priv/ldap/<realmname>.pw` | |
225 | (for example, `/etc/pve/priv/ldap/my-ldap.pw`). This file should contain a | |
226 | single line with the raw password. | |
227 | ||
228 | To verify certificates, you need to set `capath`. You can set it either | |
229 | directly to the CA certificate of your LDAP server, or to the system path | |
230 | containing all trusted CA certificates (`/etc/ssl/certs`). | |
231 | Additionally, you need to set the `verify` option, which can also be done over | |
232 | the web interface. | |
233 | ||
234 | The main configuration options for an LDAP server realm are as follows: | |
235 | ||
236 | * `Realm` (`realm`): The realm identifier for {pve} users | |
237 | ||
238 | * `Base Domain Name` (`base_dn`): The directory which users are searched under | |
239 | ||
240 | * `User Attribute Name` (`user_attr`): The LDAP attribute containing the | |
241 | username that users will log in with | |
242 | ||
243 | * `Server` (`server1`): The server hosting the LDAP directory | |
244 | ||
245 | * `Fallback Server` (`server2`): An optional fallback server address, in case | |
246 | the primary server is unreachable | |
247 | ||
248 | * `Port` (`port`): The port that the LDAP server listens on | |
249 | ||
250 | NOTE: In order to allow a particular user to authenticate using the LDAP server, | |
251 | you must also add them as a user of that realm from the {pve} server. This can | |
252 | be carried out automatically with <<pveum_ldap_sync, syncing>>. | |
253 | ||
254 | ||
255 | Microsoft Active Directory (AD) | |
256 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
257 | ||
258 | To set up Microsoft AD as a realm, a server address and authentication domain | |
259 | need to be specified. Active Directory supports most of the same properties as | |
260 | LDAP, such as an optional fallback server, port, and SSL encryption. | |
261 | Furthermore, users can be added to {pve} automatically via | |
262 | <<pveum_ldap_sync, sync>> operations, after configuration. | |
263 | ||
264 | As with LDAP, if {pve} needs to authenticate before it binds to the AD server, | |
265 | you must configure the 'Bind User' (`bind_dn`) property. This property is | |
266 | typically required by default for Microsoft AD. | |
267 | ||
268 | The main configuration settings for Microsoft Active Directory are: | |
269 | ||
270 | * `Realm` (`realm`): The realm identifier for {pve} users | |
271 | ||
272 | * `Domain` (`domain`): The AD domain of the server | |
273 | ||
274 | * `Server` (`server1`): The FQDN or IP address of the server | |
275 | ||
276 | * `Fallback Server` (`server2`): An optional fallback server address, in case | |
277 | the primary server is unreachable | |
278 | ||
279 | * `Port` (`port`): The port that the Microsoft AD server listens on | |
280 | ||
281 | [[pveum_ldap_sync]] | |
282 | Syncing LDAP-Based Realms | |
283 | ~~~~~~~~~~~~~~~~~~~~~~~~~ | |
284 | ||
285 | [thumbnail="screenshot/gui-datacenter-realm-add-ldap.png"] | |
286 | ||
287 | It's possible to automatically sync users and groups for LDAP-based realms (LDAP | |
288 | & Microsoft Active Directory), rather than having to add them to {pve} manually. | |
289 | You can access the sync options from the Add/Edit window of the web interface's | |
290 | `Authentication` panel or via the `pveum realm add/modify` commands. You can | |
291 | then carry out the sync operation from the `Authentication` panel of the GUI or | |
292 | using the following command: | |
293 | ||
294 | ---- | |
295 | pveum realm sync <realm> | |
296 | ---- | |
297 | ||
298 | Users and groups are synced to the cluster-wide configuration file, | |
299 | `/etc/pve/user.cfg`. | |
300 | ||
301 | ||
302 | Attributes to Properties | |
303 | ^^^^^^^^^^^^^^^^^^^^^^^^ | |
304 | ||
305 | If the sync response includes user attributes, they will be synced into the | |
306 | matching user property in the `user.cfg`. For example: `firstname` or | |
307 | `lastname`. | |
308 | ||
309 | If the names of the attributes are not matching the {pve} properties, you can | |
310 | set a custom field-to-field map in the config by using the `sync_attributes` | |
311 | option. | |
312 | ||
313 | How such properties are handled if anything vanishes can be controlled via the | |
314 | sync options, see below. | |
315 | ||
316 | Sync Configuration | |
317 | ^^^^^^^^^^^^^^^^^^ | |
318 | ||
319 | The configuration options for syncing LDAP-based realms can be found in the | |
320 | `Sync Options` tab of the Add/Edit window. | |
321 | ||
322 | The configuration options are as follows: | |
323 | ||
324 | * `Bind User` (`bind_dn`): Refers to the LDAP account used to query users | |
325 | and groups. This account needs access to all desired entries. If it's set, the | |
326 | search will be carried out via binding; otherwise, the search will be carried | |
327 | out anonymously. The user must be a complete LDAP formatted distinguished name | |
328 | (DN), for example, `cn=admin,dc=example,dc=com`. | |
329 | ||
330 | * Groupname attr. (group_name_attr): Represents the | |
331 | users' groups. Only entries which adhere to the usual character limitations of | |
332 | the `user.cfg` are synced. Groups are synced with `-$realm` attached to the | |
333 | name, in order to avoid naming conflicts. Please ensure that a sync does not | |
334 | overwrite manually created groups. | |
335 | ||
336 | * `User classes` (`user_classes`): Objects classes associated with users. | |
337 | ||
338 | * `Group classes` (`group_classes`): Objects classes associated with groups. | |
339 | ||
340 | * `E-Mail attribute`: If the LDAP-based server specifies user email addresses, | |
341 | these can also be included in the sync by setting the associated attribute | |
342 | here. From the command line, this is achievable through the | |
343 | `--sync_attributes` parameter. | |
344 | ||
345 | * `User Filter` (`filter`): For further filter options to target specific users. | |
346 | ||
347 | * `Group Filter` (`group_filter`): For further filter options to target specific | |
348 | groups. | |
349 | ||
350 | NOTE: Filters allow you to create a set of additional match criteria, to narrow | |
351 | down the scope of a sync. Information on available LDAP filter types and their | |
352 | usage can be found at https://ldap.com/ldap-filters/[ldap.com]. | |
353 | ||
354 | [[pveum_ldap_sync_options]] | |
355 | Sync Options | |
356 | ^^^^^^^^^^^^ | |
357 | ||
358 | [thumbnail="screenshot/gui-datacenter-realm-add-ldap-sync-options.png"] | |
359 | ||
360 | In addition to the options specified in the previous section, you can also | |
361 | configure further options that describe the behavior of the sync operation. | |
362 | ||
363 | These options are either set as parameters before the sync, or as defaults via | |
364 | the realm option `sync-defaults-options`. | |
365 | ||
366 | The main options for syncing are: | |
367 | ||
368 | * `Scope` (`scope`): The scope of what to sync. It can be either `users`, | |
369 | `groups` or `both`. | |
370 | ||
371 | * `Enable new` (`enable-new`): If set, the newly synced users are enabled and | |
372 | can log in. The default is `true`. | |
373 | ||
374 | * `Remove Vanished` (`remove-vanished`): This is a list of options which, when | |
375 | activated, determine if they are removed when they are not returned from | |
376 | the sync response. The options are: | |
377 | ||
378 | - `ACL` (`acl)`: Remove ACLs of users and groups which were not returned | |
379 | returned in the sync response. This most often makes sense together with | |
380 | `Entry`. | |
381 | ||
382 | - `Entry` (`entry`): Removes entries (i.e. users and groups) when they are | |
383 | not returned in the sync response. | |
384 | ||
385 | - `Properties` (`properties`): Removes properties of entries where the user | |
386 | in the sync response did not contain those attributes. This includes | |
387 | all properties, even those never set by a sync. Exceptions are tokens | |
388 | and the enable flag, these will be retained even with this option enabled. | |
389 | ||
390 | * `Preview` (`dry-run`): No data is written to the config. This is useful if you | |
391 | want to see which users and groups would get synced to the `user.cfg`. | |
392 | ||
393 | ||
394 | [[pveum_openid]] | |
395 | OpenID Connect | |
396 | ~~~~~~~~~~~~~~ | |
397 | ||
398 | The main OpenID Connect configuration options are: | |
399 | ||
400 | * `Issuer URL` (`issuer-url`): This is the URL of the authorization server. | |
401 | Proxmox uses the OpenID Connect Discovery protocol to automatically configure | |
402 | further details. | |
403 | + | |
404 | While it is possible to use unencrypted `http://` URLs, we strongly recommend to | |
405 | use encrypted `https://` connections. | |
406 | ||
407 | * `Realm` (`realm`): The realm identifier for {pve} users | |
408 | ||
409 | * `Client ID` (`client-id`): OpenID Client ID. | |
410 | ||
411 | * `Client Key` (`client-key`): Optional OpenID Client Key. | |
412 | ||
413 | * `Autocreate Users` (`autocreate`): Automatically create users if they do not | |
414 | exist. While authentication is done at the OpenID server, all users still need | |
415 | an entry in the {pve} user configuration. You can either add them manually, or | |
416 | use the `autocreate` option to automatically add new users. | |
417 | ||
418 | * `Username Claim` (`username-claim`): OpenID claim used to generate the unique | |
419 | username (`subject`, `username` or `email`). | |
420 | ||
421 | Username mapping | |
422 | ^^^^^^^^^^^^^^^^ | |
423 | ||
424 | The OpenID Connect specification defines a single unique attribute | |
425 | ('claim' in OpenID terms) named `subject`. By default, we use the | |
426 | value of this attribute to generate {pve} usernames, by simple adding | |
427 | `@` and the realm name: `${subject}@${realm}`. | |
428 | ||
429 | Unfortunately, most OpenID servers use random strings for `subject`, like | |
430 | `DGH76OKH34BNG3245SB`, so a typical username would look like | |
431 | `DGH76OKH34BNG3245SB@yourrealm`. While unique, it is difficult for | |
432 | humans to remember such random strings, making it quite impossible to | |
433 | associate real users with this. | |
434 | ||
435 | The `username-claim` setting allows you to use other attributes for | |
436 | the username mapping. Setting it to `username` is preferred if the | |
437 | OpenID Connect server provides that attribute and guarantees its | |
438 | uniqueness. | |
439 | ||
440 | Another option is to use `email`, which also yields human readable | |
441 | usernames. Again, only use this setting if the server guarantees the | |
442 | uniqueness of this attribute. | |
443 | ||
444 | Examples | |
445 | ^^^^^^^^ | |
446 | ||
447 | Here is an example of creating an OpenID realm using Google. You need to | |
448 | replace `--client-id` and `--client-key` with the values | |
449 | from your Google OpenID settings. | |
450 | ||
451 | ---- | |
452 | pveum realm add myrealm1 --type openid --issuer-url https://accounts.google.com --client-id XXXX --client-key YYYY --username-claim email | |
453 | ---- | |
454 | ||
455 | The above command uses `--username-claim email`, so that the usernames on the | |
456 | {pve} side look like `example.user@google.com@myrealm1`. | |
457 | ||
458 | Keycloak (https://www.keycloak.org/) is a popular open source Identity | |
459 | and Access Management tool, which supports OpenID Connect. In the following | |
460 | example, you need to replace the `--issuer-url` and `--client-id` with | |
461 | your information: | |
462 | ||
463 | ---- | |
464 | pveum realm add myrealm2 --type openid --issuer-url https://your.server:8080/auth/realms/your-realm --client-id XXX --username-claim username | |
465 | ---- | |
466 | ||
467 | Using `--username-claim username` enables simple usernames on the | |
468 | {pve} side, like `example.user@myrealm2`. | |
469 | ||
470 | WARNING: You need to ensure that the user is not allowed to edit | |
471 | the username setting themselves (on the Keycloak server). | |
472 | ||
473 | ||
474 | [[pveum_tfa_auth]] | |
475 | Two-Factor Authentication | |
476 | ------------------------- | |
477 | ||
478 | There are two ways to use two-factor authentication: | |
479 | ||
480 | It can be required by the authentication realm, either via 'TOTP' | |
481 | (Time-based One-Time Password) or 'YubiKey OTP'. In this case, a newly | |
482 | created user needs to have their keys added immediately, as there is no way to | |
483 | log in without the second factor. In the case of 'TOTP', users can | |
484 | also change the 'TOTP' later on, provided they can log in first. | |
485 | ||
486 | Alternatively, users can choose to opt-in to two-factor authentication | |
487 | later on, even if the realm does not enforce it. | |
488 | ||
489 | Available Second Factors | |
490 | ~~~~~~~~~~~~~~~~~~~~~~~~ | |
491 | ||
492 | You can set up multiple second factors, in order to avoid a situation in | |
493 | which losing your smartphone or security key locks you out of your | |
494 | account permanently. | |
495 | ||
496 | The following two-factor authentication methods are available in | |
497 | addition to realm-enforced TOTP and YubiKey OTP: | |
498 | ||
499 | * User configured TOTP | |
500 | (https://en.wikipedia.org/wiki/Time-based_One-Time_Password[Time-based One-Time Password]). | |
501 | A short code derived from a shared secret and the current time, it changes | |
502 | every 30 seconds. | |
503 | * WebAuthn (https://en.wikipedia.org/wiki/WebAuthn[Web Authentication]). | |
504 | A general standard for authentication. It is implemented by various | |
505 | security devices, like hardware keys or trusted platform modules (TPM) | |
506 | from a computer or smart phone. | |
507 | * Single use Recovery Keys. A list of keys which should either be | |
508 | printed out and locked in a secure place or saved digitally in an | |
509 | electronic vault. Each key can be used only once. These are perfect for | |
510 | ensuring that you are not locked out, even if all of your other second | |
511 | factors are lost or corrupt. | |
512 | ||
513 | Before WebAuthn was supported, U2F could be setup by the user. Existing | |
514 | U2F factors can still be used, but it is recommended to switch to | |
515 | WebAuthn, once it is configured on the server. | |
516 | ||
517 | Realm Enforced Two-Factor Authentication | |
518 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
519 | ||
520 | This can be done by selecting one of the available methods via the | |
521 | 'TFA' dropdown box when adding or editing an Authentication Realm. | |
522 | When a realm has TFA enabled, it becomes a requirement, and only users | |
523 | with configured TFA will be able to log in. | |
524 | ||
525 | Currently there are two methods available: | |
526 | ||
527 | Time-based OATH (TOTP):: This uses the standard HMAC-SHA1 algorithm, | |
528 | where the current time is hashed with the user's configured key. The | |
529 | time step and password length parameters are configurable. | |
530 | + | |
531 | A user can have multiple keys configured (separated by spaces), and the keys | |
532 | can be specified in Base32 (RFC3548) or hexadecimal notation. | |
533 | + | |
534 | {pve} provides a key generation tool (`oathkeygen`) which prints out a random | |
535 | key in Base32 notation, that can be used directly with various OTP tools, such | |
536 | as the `oathtool` command line tool, or on Android Google Authenticator, | |
537 | FreeOTP, andOTP or similar applications. | |
538 | ||
539 | YubiKey OTP:: | |
540 | For authenticating via a YubiKey a Yubico API ID, API KEY and validation | |
541 | server URL must be configured, and users must have a YubiKey available. In | |
542 | order to get the key ID from a YubiKey, you can trigger the YubiKey once | |
543 | after connecting it via USB, and copy the first 12 characters of the typed | |
544 | password into the user's 'Key IDs' field. | |
545 | ||
546 | Please refer to the https://developers.yubico.com/OTP/[YubiKey OTP] | |
547 | documentation for how to use the | |
548 | https://www.yubico.com/products/services-software/yubicloud/[YubiCloud] or | |
549 | https://developers.yubico.com/Software_Projects/Yubico_OTP/YubiCloud_Validation_Servers/[host your own verification server]. | |
550 | ||
551 | [[pveum_user_configured_totp]] | |
552 | User Configured TOTP Authentication | |
553 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
554 | ||
555 | Users can choose to enable 'TOTP' or 'WebAuthn' as a second factor on login, via | |
556 | the 'TFA' button in the user list (unless the realm enforces 'YubiKey OTP'). | |
557 | ||
558 | Users can always add and use one time 'Recovery Keys'. | |
559 | ||
560 | [thumbnail="screenshot/gui-datacenter-two-factor.png"] | |
561 | ||
562 | After opening the 'TFA' window, the user is presented with a dialog to set up | |
563 | 'TOTP' authentication. The 'Secret' field contains the key, which can be | |
564 | randomly generated via the 'Randomize' button. An optional 'Issuer Name' can be | |
565 | added to provide information to the 'TOTP' app about what the key belongs to. | |
566 | Most 'TOTP' apps will show the issuer name together with the corresponding | |
567 | 'OTP' values. The username is also included in the QR code for the 'TOTP' app. | |
568 | ||
569 | After generating a key, a QR code will be displayed, which can be used with most | |
570 | OTP apps such as FreeOTP. The user then needs to verify the current user | |
571 | password (unless logged in as 'root'), as well as the ability to correctly use | |
572 | the 'TOTP' key, by typing the current 'OTP' value into the 'Verification Code' | |
573 | field and pressing the 'Apply' button. | |
574 | ||
575 | [[user_tfa_setup_totp]] | |
576 | === TOTP | |
577 | ||
578 | [thumbnail="screenshot/pve-gui-tfa-add-totp.png"] | |
579 | ||
580 | There is no server setup required. Simply install a TOTP app on your | |
581 | smartphone (for example, https://freeotp.github.io/[FreeOTP]) and use | |
582 | the Proxmox Backup Server web-interface to add a TOTP factor. | |
583 | ||
584 | [[user_tfa_setup_webauthn]] | |
585 | === WebAuthn | |
586 | ||
587 | For WebAuthn to work, you need to have two things: | |
588 | ||
589 | * A trusted HTTPS certificate (for example, by using | |
590 | https://pve.proxmox.com/wiki/Certificate_Management[Let's Encrypt]). | |
591 | While it probably works with an untrusted certificate, some browsers may | |
592 | warn or refuse WebAuthn operations if it is not trusted. | |
593 | * Setup the WebAuthn configuration (see *Datacenter -> Options -> | |
594 | WebAuthn Settings* in the Proxmox VE web interface). This can be | |
595 | auto-filled in most setups. | |
596 | ||
597 | Once you have fulfilled both of these requirements, you can add a WebAuthn | |
598 | configuration in the *Two Factor* panel under *Datacenter -> Permissions -> Two | |
599 | Factor*. | |
600 | ||
601 | [[user_tfa_setup_recovery_keys]] | |
602 | === Recovery Keys | |
603 | ||
604 | [thumbnail="screenshot/pve-gui-tfa-add-recovery-keys.png"] | |
605 | ||
606 | Recovery key codes do not need any preparation; you can simply create a | |
607 | set of recovery keys in the *Two Factor* panel under *Datacenter -> Permissions | |
608 | -> Two Factor*. | |
609 | ||
610 | NOTE: There can only be one set of single-use recovery keys per user at any | |
611 | time. | |
612 | ||
613 | ||
614 | [[pveum_configure_webauthn]] | |
615 | Server Side Webauthn Configuration | |
616 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
617 | ||
618 | [thumbnail="screenshot/gui-datacenter-webauthn-edit.png"] | |
619 | ||
620 | To allow users to use 'WebAuthn' authentication, it is necessaary to use a valid | |
621 | domain with a valid SSL certificate, otherwise some browsers may warn or refuse | |
622 | to authenticate altogether. | |
623 | ||
624 | NOTE: Changing the 'WebAuthn' configuration may render all existing 'WebAuthn' | |
625 | registrations unusable! | |
626 | ||
627 | This is done via `/etc/pve/datacenter.cfg`. For instance: | |
628 | ||
629 | ---- | |
630 | webauthn: rp=mypve.example.com,origin=https://mypve.example.com:8006,id=mypve.example.com | |
631 | ---- | |
632 | ||
633 | [[pveum_configure_u2f]] | |
634 | Server Side U2F Configuration | |
635 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
636 | ||
637 | NOTE: It is recommended to use WebAuthn instead. | |
638 | ||
639 | To allow users to use 'U2F' authentication, it may be necessary to use a valid | |
640 | domain with a valid SSL certificate, otherwise, some browsers may print | |
641 | a warning or reject U2F usage altogether. Initially, an 'AppId' | |
642 | footnote:[AppId https://developers.yubico.com/U2F/App_ID.html] | |
643 | needs to be configured. | |
644 | ||
645 | NOTE: Changing the 'AppId' will render all existing 'U2F' registrations | |
646 | unusable! | |
647 | ||
648 | This is done via `/etc/pve/datacenter.cfg`. For instance: | |
649 | ||
650 | ---- | |
651 | u2f: appid=https://mypve.example.com:8006 | |
652 | ---- | |
653 | ||
654 | For a single node, the 'AppId' can simply be the address of the web-interface, | |
655 | exactly as it is used in the browser, including the 'https://' and the port, as | |
656 | shown above. Please note that some browsers may be more strict than others when | |
657 | matching 'AppIds'. | |
658 | ||
659 | When using multiple nodes, it is best to have a separate `https` server | |
660 | providing an `appid.json` | |
661 | footnote:[Multi-facet apps: https://developers.yubico.com/U2F/App_ID.html] | |
662 | file, as it seems to be compatible with most | |
663 | browsers. If all nodes use subdomains of the same top level domain, it may be | |
664 | enough to use the TLD as 'AppId'. It should however be noted that some browsers | |
665 | may not accept this. | |
666 | ||
667 | NOTE: A bad 'AppId' will usually produce an error, but we have encountered | |
668 | situations when this does not happen, particularly when using a top level domain | |
669 | 'AppId' for a node that is accessed via a subdomain in Chromium. For this reason | |
670 | it is recommended to test the configuration with multiple browsers, as changing | |
671 | the 'AppId' later will render existing 'U2F' registrations unusable. | |
672 | ||
673 | [[pveum_user_configured_u2f]] | |
674 | Activating U2F as a User | |
675 | ~~~~~~~~~~~~~~~~~~~~~~~~ | |
676 | ||
677 | To enable 'U2F' authentication, open the 'TFA' window's 'U2F' tab, type in the | |
678 | current password (unless logged in as root), and press the 'Register' button. | |
679 | If the server is set up correctly and the browser accepts the server's provided | |
680 | 'AppId', a message will appear prompting the user to press the button on the | |
681 | 'U2F' device (if it is a 'YubiKey', the button light should be toggling on and | |
682 | off steadily, roughly twice per second). | |
683 | ||
684 | Firefox users may need to enable 'security.webauth.u2f' via 'about:config' | |
685 | before they can use a 'U2F' token. | |
686 | ||
687 | [[pveum_permission_management]] | |
688 | Permission Management | |
689 | --------------------- | |
690 | ||
691 | In order for a user to perform an action (such as listing, modifying or | |
692 | deleting parts of a VM's configuration), the user needs to have the | |
693 | appropriate permissions. | |
694 | ||
695 | {pve} uses a role and path based permission management system. An entry in | |
696 | the permissions table allows a user, group or token to take on a specific role | |
697 | when accessing an 'object' or 'path'. This means that such an access rule can | |
698 | be represented as a triple of '(path, user, role)', '(path, group, | |
699 | role)' or '(path, token, role)', with the role containing a set of allowed | |
700 | actions, and the path representing the target of these actions. | |
701 | ||
702 | ||
703 | [[pveum_roles]] | |
704 | Roles | |
705 | ~~~~~ | |
706 | ||
707 | A role is simply a list of privileges. Proxmox VE comes with a number | |
708 | of predefined roles, which satisfy most requirements. | |
709 | ||
710 | * `Administrator`: has full privileges | |
711 | * `NoAccess`: has no privileges (used to forbid access) | |
712 | * `PVEAdmin`: can do most tasks, but has no rights to modify system settings (`Sys.PowerMgmt`, `Sys.Modify`, `Realm.Allocate`) | |
713 | * `PVEAuditor`: has read only access | |
714 | * `PVEDatastoreAdmin`: create and allocate backup space and templates | |
715 | * `PVEDatastoreUser`: allocate backup space and view storage | |
716 | * `PVEPoolAdmin`: allocate pools | |
717 | * `PVESysAdmin`: User ACLs, audit, system console and system logs | |
718 | * `PVETemplateUser`: view and clone templates | |
719 | * `PVEUserAdmin`: manage users | |
720 | * `PVEVMAdmin`: fully administer VMs | |
721 | * `PVEVMUser`: view, backup, configure CD-ROM, VM console, VM power management | |
722 | ||
723 | You can see the whole set of predefined roles in the GUI. | |
724 | ||
725 | You can add new roles via the GUI or the command line. | |
726 | ||
727 | [thumbnail="screenshot/gui-datacenter-role-add.png"] | |
728 | From the GUI, navigate to the 'Permissions -> Roles' tab from 'Datacenter' and | |
729 | click on the 'Create' button. There you can set a role name and select any | |
730 | desired privileges from the 'Privileges' drop-down menu. | |
731 | ||
732 | To add a role through the command line, you can use the 'pveum' CLI tool, for | |
733 | example: | |
734 | [source,bash] | |
735 | ---- | |
736 | pveum role add PVE_Power-only --privs "VM.PowerMgmt VM.Console" | |
737 | pveum role add Sys_Power-only --privs "Sys.PowerMgmt Sys.Console" | |
738 | ---- | |
739 | ||
740 | ||
741 | Privileges | |
742 | ~~~~~~~~~~ | |
743 | ||
744 | A privilege is the right to perform a specific action. To simplify | |
745 | management, lists of privileges are grouped into roles, which can then | |
746 | be used in the permission table. Note that privileges cannot be directly | |
747 | assigned to users and paths without being part of a role. | |
748 | ||
749 | We currently support the following privileges: | |
750 | ||
751 | Node / System related privileges:: | |
752 | ||
753 | * `Permissions.Modify`: modify access permissions | |
754 | * `Sys.PowerMgmt`: node power management (start, stop, reset, shutdown, ...) | |
755 | * `Sys.Console`: console access to node | |
756 | * `Sys.Syslog`: view syslog | |
757 | * `Sys.Audit`: view node status/config, Corosync cluster config, and HA config | |
758 | * `Sys.Modify`: create/modify/remove node network parameters | |
759 | * `Sys.Incoming`: allow incoming data streams from other clusters (experimental) | |
760 | * `Group.Allocate`: create/modify/remove groups | |
761 | * `Pool.Allocate`: create/modify/remove a pool | |
762 | * `Pool.Audit`: view a pool | |
763 | * `Realm.Allocate`: create/modify/remove authentication realms | |
764 | * `Realm.AllocateUser`: assign user to a realm | |
765 | * `User.Modify`: create/modify/remove user access and details. | |
766 | ||
767 | Virtual machine related privileges:: | |
768 | ||
769 | * `VM.Allocate`: create/remove VM on a server | |
770 | * `VM.Migrate`: migrate VM to alternate server on cluster | |
771 | * `VM.PowerMgmt`: power management (start, stop, reset, shutdown, ...) | |
772 | * `VM.Console`: console access to VM | |
773 | * `VM.Monitor`: access to VM monitor (kvm) | |
774 | * `VM.Backup`: backup/restore VMs | |
775 | * `VM.Audit`: view VM config | |
776 | * `VM.Clone`: clone/copy a VM | |
777 | * `VM.Config.Disk`: add/modify/remove disks | |
778 | * `VM.Config.CDROM`: eject/change CD-ROM | |
779 | * `VM.Config.CPU`: modify CPU settings | |
780 | * `VM.Config.Memory`: modify memory settings | |
781 | * `VM.Config.Network`: add/modify/remove network devices | |
782 | * `VM.Config.HWType`: modify emulated hardware types | |
783 | * `VM.Config.Options`: modify any other VM configuration | |
784 | * `VM.Config.Cloudinit`: modify Cloud-init parameters | |
785 | * `VM.Snapshot`: create/delete VM snapshots | |
786 | ||
787 | Storage related privileges:: | |
788 | ||
789 | * `Datastore.Allocate`: create/modify/remove a datastore and delete volumes | |
790 | * `Datastore.AllocateSpace`: allocate space on a datastore | |
791 | * `Datastore.AllocateTemplate`: allocate/upload templates and ISO images | |
792 | * `Datastore.Audit`: view/browse a datastore | |
793 | ||
794 | ||
795 | Objects and Paths | |
796 | ~~~~~~~~~~~~~~~~~ | |
797 | ||
798 | Access permissions are assigned to objects, such as virtual machines, | |
799 | storages or resource pools. | |
800 | We use file system like paths to address these objects. These paths form a | |
801 | natural tree, and permissions of higher levels (shorter paths) can | |
802 | optionally be propagated down within this hierarchy. | |
803 | ||
804 | [[pveum_templated_paths]] | |
805 | Paths can be templated. When an API call requires permissions on a | |
806 | templated path, the path may contain references to parameters of the API | |
807 | call. These references are specified in curly braces. Some parameters are | |
808 | implicitly taken from the API call's URI. For instance, the permission path | |
809 | `/nodes/{node}` when calling '/nodes/mynode/status' requires permissions on | |
810 | `/nodes/mynode`, while the path `{path}` in a PUT request to `/access/acl` | |
811 | refers to the method's `path` parameter. | |
812 | ||
813 | Some examples are: | |
814 | ||
815 | * `/nodes/{node}`: Access to {pve} server machines | |
816 | * `/vms`: Covers all VMs | |
817 | * `/vms/{vmid}`: Access to specific VMs | |
818 | * `/storage/{storeid}`: Access to a specific storage | |
819 | * `/pool/{poolname}`: Access to resources contained in a specific <<pveum_pools,pool>> | |
820 | * `/access/groups`: Group administration | |
821 | * `/access/realms/{realmid}`: Administrative access to realms | |
822 | ||
823 | ||
824 | Inheritance | |
825 | ^^^^^^^^^^^ | |
826 | ||
827 | As mentioned earlier, object paths form a file system like tree, and | |
828 | permissions can be inherited by objects down that tree (the propagate flag is | |
829 | set by default). We use the following inheritance rules: | |
830 | ||
831 | * Permissions for individual users always replace group permissions. | |
832 | * Permissions for groups apply when the user is member of that group. | |
833 | * Permissions on deeper levels replace those inherited from an upper level. | |
834 | ||
835 | Additionally, privilege separated tokens can never have permissions on any | |
836 | given path that their associated user does not have. | |
837 | ||
838 | [[pveum_pools]] | |
839 | Pools | |
840 | ~~~~~ | |
841 | ||
842 | Pools can be used to group a set of virtual machines and datastores. You can | |
843 | then simply set permissions on pools (`/pool/{poolid}`), which are inherited by | |
844 | all pool members. This is a great way to simplify access control. | |
845 | ||
846 | ||
847 | Which Permissions Do I Need? | |
848 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
849 | ||
850 | The required API permissions are documented for each individual | |
851 | method, and can be found at https://pve.proxmox.com/pve-docs/api-viewer/. | |
852 | ||
853 | The permissions are specified as a list, which can be interpreted as a | |
854 | tree of logic and access-check functions: | |
855 | ||
856 | `["and", <subtests>...]` and `["or", <subtests>...]`:: | |
857 | Each(`and`) or any(`or`) further element in the current list has to be true. | |
858 | ||
859 | `["perm", <path>, [ <privileges>... ], <options>...]`:: | |
860 | The `path` is a templated parameter (see | |
861 | <<pveum_templated_paths,Objects and Paths>>). All (or, if the `any` | |
862 | option is used, any) of the listed | |
863 | privileges must be allowed on the specified path. If a `require-param` | |
864 | option is specified, then its specified parameter is required even if the | |
865 | API call's schema otherwise lists it as being optional. | |
866 | ||
867 | `["userid-group", [ <privileges>... ], <options>...]`:: | |
868 | The caller must have any of the listed privileges on `/access/groups`. In | |
869 | addition, there are two possible checks, depending on whether the | |
870 | `groups_param` option is set: | |
871 | + | |
872 | * `groups_param` is set: The API call has a non-optional `groups` parameter | |
873 | and the caller must have any of the listed privileges on all of the listed | |
874 | groups. | |
875 | * `groups_param` is not set: The user passed via the `userid` parameter | |
876 | must exist and be part of a group on which the caller has any of the listed | |
877 | privileges (via the `/access/groups/<group>` path). | |
878 | ||
879 | `["userid-param", "self"]`:: | |
880 | The value provided for the API call's `userid` parameter must refer to the | |
881 | user performing the action (usually in conjunction with `or`, to allow | |
882 | users to perform an action on themselves, even if they don't have elevated | |
883 | privileges). | |
884 | ||
885 | `["userid-param", "Realm.AllocateUser"]`:: | |
886 | The user needs `Realm.AllocateUser` access to `/access/realm/<realm>`, with | |
887 | `<realm>` referring to the realm of the user passed via the `userid` | |
888 | parameter. Note that the user does not need to exist in order to be | |
889 | associated with a realm, since user IDs are passed in the form of | |
890 | `<username>@<realm>`. | |
891 | ||
892 | `["perm-modify", <path>]`:: | |
893 | The `path` is a templated parameter (see | |
894 | <<pveum_templated_paths,Objects and Paths>>). The user needs either the | |
895 | `Permissions.Modify` privilege or, | |
896 | depending on the path, the following privileges as a possible substitute: | |
897 | + | |
898 | * `/storage/...`: additionally requires 'Datastore.Allocate` | |
899 | * `/vms/...`: additionally requires 'VM.Allocate` | |
900 | * `/pool/...`: additionally requires 'Pool.Allocate` | |
901 | + | |
902 | If the path is empty, `Permission.Modify` on `/access` is required. | |
903 | ||
904 | Command Line Tool | |
905 | ----------------- | |
906 | ||
907 | Most users will simply use the GUI to manage users. But there is also | |
908 | a fully featured command line tool called `pveum` (short for ``**P**roxmox | |
909 | **VE** **U**ser **M**anager''). Please note that all Proxmox VE command | |
910 | line tools are wrappers around the API, so you can also access those | |
911 | functions through the REST API. | |
912 | ||
913 | Here are some simple usage examples. To show help, type: | |
914 | ||
915 | [source,bash] | |
916 | pveum | |
917 | ||
918 | or (to show detailed help about a specific command) | |
919 | ||
920 | [source,bash] | |
921 | pveum help user add | |
922 | ||
923 | Create a new user: | |
924 | ||
925 | [source,bash] | |
926 | pveum user add testuser@pve -comment "Just a test" | |
927 | ||
928 | Set or change the password (not all realms support this): | |
929 | ||
930 | [source,bash] | |
931 | pveum passwd testuser@pve | |
932 | ||
933 | Disable a user: | |
934 | ||
935 | [source,bash] | |
936 | pveum user modify testuser@pve -enable 0 | |
937 | ||
938 | Create a new group: | |
939 | ||
940 | [source,bash] | |
941 | pveum group add testgroup | |
942 | ||
943 | Create a new role: | |
944 | ||
945 | [source,bash] | |
946 | pveum role add PVE_Power-only -privs "VM.PowerMgmt VM.Console" | |
947 | ||

949 | Real World Examples | |
950 | ------------------- | |
951 | ||
952 | ||
953 | Administrator Group | |
954 | ~~~~~~~~~~~~~~~~~~~ | |
955 | ||
956 | It is possible that an administrator would want to create a group of users with | |
957 | full administrator rights (without using the root account). | |
958 | ||
959 | To do this, first define the group: | |
960 | ||
961 | [source,bash] | |
962 | pveum group add admin -comment "System Administrators" | |
963 | ||
964 | Then assign the role: | |
965 | ||
966 | [source,bash] | |
967 | pveum acl modify / -group admin -role Administrator | |
968 | ||
969 | Finally, you can add users to the new 'admin' group: | |
970 | ||
971 | [source,bash] | |
972 | pveum user modify testuser@pve -group admin | |
973 | ||
974 | ||
975 | Auditors | |
976 | ~~~~~~~~ | |
977 | ||
978 | You can give read only access to users by assigning the `PVEAuditor` | |
979 | role to users or groups. | |
980 | ||
981 | Example 1: Allow user `joe@pve` to see everything | |
982 | ||
983 | [source,bash] | |
984 | pveum acl modify / -user joe@pve -role PVEAuditor | |
985 | ||
986 | Example 2: Allow user `joe@pve` to see all virtual machines | |
987 | ||
988 | [source,bash] | |
989 | pveum acl modify /vms -user joe@pve -role PVEAuditor | |
990 | ||
991 | ||
992 | Delegate User Management | |
993 | ~~~~~~~~~~~~~~~~~~~~~~~~ | |
994 | ||
995 | If you want to delegate user management to user `joe@pve`, you can do | |
996 | that with: | |
997 | ||
998 | [source,bash] | |
999 | pveum acl modify /access -user joe@pve -role PVEUserAdmin | |
1000 | ||
1001 | User `joe@pve` can now add and remove users, and change other user attributes, | |
1002 | such as passwords. This is a very powerful role, and you most | |
1003 | likely want to limit it to selected realms and groups. The following | |
1004 | example allows `joe@pve` to modify users within the realm `pve`, if they | |
1005 | are members of group `customers`: | |
1006 | ||
1007 | [source,bash] | |
1008 | pveum acl modify /access/realm/pve -user joe@pve -role PVEUserAdmin | |
1009 | pveum acl modify /access/groups/customers -user joe@pve -role PVEUserAdmin | |
1010 | ||
1011 | NOTE: The user is able to add other users, but only if they are | |
1012 | members of the group `customers` and within the realm `pve`. | |
1013 | ||
1014 | Limited API Token for Monitoring | |
1015 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
1016 | ||
1017 | Permissions on API tokens are always a subset of those of their corresponding | |
1018 | user, meaning that an API token can't be used to carry out a task that the | |
1019 | backing user has no permission to do. This section will demonstrate how you can | |
1020 | use an API token with separate privileges, to limit the token owner's | |
1021 | permissions further. | |
1022 | ||
1023 | Give the user `joe@pve` the role PVEVMAdmin on all VMs: | |
1024 | ||
1025 | [source,bash] | |
1026 | pveum acl modify /vms -user joe@pve -role PVEVMAdmin | |
1027 | ||
1028 | Add a new API token with separate privileges, which is only allowed to view VM | |
1029 | information (for example, for monitoring purposes): | |
1030 | ||
1031 | [source,bash] | |
1032 | pveum user token add joe@pve monitoring -privsep 1 | |
1033 | pveum acl modify /vms -token 'joe@pve!monitoring' -role PVEAuditor | |
1034 | ||
1035 | Verify the permissions of the user and token: | |
1036 | ||
1037 | [source,bash] | |
1038 | pveum user permissions joe@pve | |
1039 | pveum user token permissions joe@pve monitoring | |
1040 | ||
1041 | Resource Pools | |
1042 | ~~~~~~~~~~~~~~ | |
1043 | ||
1044 | An enterprise is usually structured into several smaller departments, and it is | |
1045 | common that you want to assign resources and delegate management tasks to each | |
1046 | of these. Let's assume that you want to set up a pool for a software development | |
1047 | department. First, create a group: | |
1048 | ||
1049 | [source,bash] | |
1050 | pveum group add developers -comment "Our software developers" | |
1051 | ||
1052 | Now we create a new user which is a member of that group: | |
1053 | ||
1054 | [source,bash] | |
1055 | pveum user add developer1@pve -group developers -password | |
1056 | ||
1057 | NOTE: The "-password" parameter will prompt you for a password | |
1058 | ||
1059 | Then we create a resource pool for our development department to use: | |
1060 | ||
1061 | [source,bash] | |
1062 | pveum pool add dev-pool --comment "IT development pool" | |
1063 | ||
1064 | Finally, we can assign permissions to that pool: | |
1065 | ||
1066 | [source,bash] | |
1067 | pveum acl modify /pool/dev-pool/ -group developers -role PVEAdmin | |
1068 | ||
1069 | Our software developers can now administer the resources assigned to | |
1070 | that pool. | |
