+Create an authorization object that will control access to network services.
+
+The @option{identity} parameter is identifies the user and its format
+depends on the network service that authorization object is associated
+with. For authorizing based on TLS x509 certificates, the identity must
+be the x509 distinguished name. Note that care must be taken to escape
+any commas in the distinguished name.
+
+An example authorization object to validate a x509 distinguished name
+would look like:
+@example
+ # $QEMU \
+ ...
+ -object 'authz-simple,id=auth0,identity=CN=laptop.example.com,,O=Example Org,,L=London,,ST=London,,C=GB' \
+ ...
+@end example
+
+Note the use of quotes due to the x509 distinguished name containing
+whitespace, and escaping of ','.
