/**
* 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
*
