-Objects and Paths
-~~~~~~~~~~~~~~~~~
-
-Access permissions are assigned to objects, such as a virtual machines
-(`/vms/{vmid}`) or a storage (`/storage/{storeid}`) or a pool of
-resources (`/pool/{poolname}`). We use file system like paths to
-address those objects. Those paths form a natural tree, and
-permissions can be inherited down that hierarchy.

Privileges
~~~~~~~~~~
* `Sys.PowerMgmt`: Node power management (start, stop, reset, shutdown, ...)
* `Sys.Console`: console access to Node
* `Sys.Syslog`: view Syslog
-* `Sys.Audit`: view node status/config
+* `Sys.Audit`: view node status/config, Corosync cluster config and HA config
* `Sys.Modify`: create/remove/modify node network parameters
* `Group.Allocate`: create/remove/modify groups
* `Pool.Allocate`: create/remove/modify a pool
* `Datastore.Audit`: view/browse a datastore
-Permissions
-~~~~~~~~~~~
+Objects and Paths
+~~~~~~~~~~~~~~~~~
+
+Access permissions are assigned to objects, such as a virtual machines,
+storages or pools of resources.
+We use file system like paths to address these objects. These paths form a
+natural tree, and permissions of higher levels (shorter path) can
+optionally be propagated down within this hierarchy.
+
+[[pveum_templated_paths]]
+Paths can be templated. When an API call requires permissions on a
+templated path, the path may contain references to parameters of the API
+call. These references are specified in curly braces. Some parameters are
+implicitly taken from the API call's URI. For instance the permission path
+`/nodes/{node}` when calling '/nodes/mynode/status' requires permissions on
+`/nodes/mynode`, while the path `{path}` in a PUT request to `/access/acl`
+refers to the method's `path` parameter.
-Permissions are the way we control access to objects. In technical
-terms they are simply a triple containing `<path,user,role>`. This
-concept is also known as access control lists. Each permission
-specifies a subject (user or group) and a role (set of privileges) on
-a specific path.
+Some examples are:
-When a subject requests an action on an object, the framework looks up
-the roles assigned to that subject (using the object path). The set of
-roles defines the granted privileges.
+* `/nodes/{node}`: Access to {pve} server machines
+* `/vms`: Covers all VMs
+* `/vms/{vmid}`: Access to specific VMs
+* `/storage/{storeid}`: Access to a storages
+* `/pool/{poolname}`: Access to VMs part of a <<pveum_pools,pool>>
+* `/access/groups`: Group administration
+* `/access/realms/{realmid}`: Administrative access to realms
Inheritance
* Permissions replace the ones inherited from an upper level.
