/**
|
|
* QAuthZPAM:
|
|
*
|
|
* This authorization driver provides a PAM mechanism
|
|
* for granting access by matching user names against a
|
|
* list of globs. Each match rule has an associated policy
|
|
* and a catch all policy applies if no rule matches
|
|
*
|
|
* To create an instance of this class via QMP:
|
|
*
|
|
* {
|
|
* "execute": "object-add",
|
|
* "arguments": {
|
|
* "qom-type": "authz-pam",
|
|
* "id": "authz0",
|
|
* "parameters": {
|
|
* "service": "qemu-vnc-tls"
|
|
* }
|
|
* }
|
|
* }
|
|
*
|
|
* The driver only uses the PAM "account" verification
|
|
* subsystem. The above config would require a config
|
|
* file /etc/pam.d/qemu-vnc-tls. For a simple file
|
|
* lookup it would contain
|
|
*
|
|
* account requisite pam_listfile.so item=user sense=allow \
|
|
* file=/etc/qemu/vnc.allow
|
|
*
|
|
* The external file would then contain a list of usernames.
|
|
* If x509 cert was being used as the username, a suitable
|
|
* entry would match the distinguish name:
|
|
*
|
|
* CN=laptop.berrange.com,O=Berrange Home,L=London,ST=London,C=GB
|
|
*
|
|
* On the command line it can be created using
|
|
*
|
|
* -object authz-pam,id=authz0,service=qemu-vnc-tls
|
|
*
