/**
 * The #GDBusAuthObserver type provides a mechanism for participating
 * in how a #GDBusServer (or a #GDBusConnection) authenticates remote
 * peers. Simply instantiate a #GDBusAuthObserver and connect to the
 * signals you are interested in. Note that new signals may be added
 * in the future
 * 
 * ## Controlling Authentication # {#auth-observer}
 * 
 * For example, if you only want to allow D-Bus connections from
 * processes owned by the same uid as the server, you would use a
 * signal handler like the following:
 * 
 * |[<!-- language="C" -->
 * static gboolean
 * on_authorize_authenticated_peer (GDBusAuthObserver *observer,
 * GIOStream         *stream,
 * GCredentials      *credentials,
 * gpointer           user_data)
 * {
 * gboolean authorized;
 * 
 * authorized = FALSE;
 * if (credentials != NULL)
 * {
 * GCredentials *own_credentials;
 * own_credentials = g_credentials_new ();
 * if (g_credentials_is_same_user (credentials, own_credentials, NULL))
 * authorized = TRUE;
 * g_object_unref (own_credentials);
 * }
 * 
 * return authorized;
 * }
 * ]|

 * Since: 2.26
