| 36 | * QAuthZPAM: | |
| 37 | * | |
| 38 | * This authorization driver provides a PAM mechanism | |
| 39 | * for granting access by matching user names against a | |
| 40 | * list of globs. Each match rule has an associated policy | |
| 41 | * and a catch all policy applies if no rule matches | |
| 42 | * | |
| 43 | * To create an instance of this class via QMP: | |
| 44 | * | |
| 45 | * { | |
| 46 | * "execute": "object-add", | |
| 47 | * "arguments": { | |
| 48 | * "qom-type": "authz-pam", | |
| 49 | * "id": "authz0", | |
| 50 | * "parameters": { | |
| 51 | * "service": "qemu-vnc-tls" | |
| 52 | * } | |
| 53 | * } | |
| 54 | * } | |
| 55 | * | |
| 56 | * The driver only uses the PAM "account" verification | |
| 57 | * subsystem. The above config would require a config | |
| 58 | * file /etc/pam.d/qemu-vnc-tls. For a simple file | |
| 59 | * lookup it would contain | |
| 60 | * | |
| 61 | * account requisite pam_listfile.so item=user sense=allow \ | |
| 62 | * file=/etc/qemu/vnc.allow | |
| 63 | * | |
| 64 | * The external file would then contain a list of usernames. | |
| 65 | * If x509 cert was being used as the username, a suitable | |
| 66 | * entry would match the distinguish name: | |
| 67 | * | |
| 68 | * CN=laptop.berrange.com,O=Berrange Home,L=London,ST=London,C=GB | |
| 69 | * | |
| 70 | * On the command line it can be created using | |
| 71 | * | |
| 72 | * -object authz-pam,id=authz0,service=qemu-vnc-tls | |
| 73 | * | |
