+/**
+ * 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
+ *
