/**
 * 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 Mechanisms
 * 
 * By default, a #GDBusServer or server-side #GDBusConnection will allow
 * any authentication mechanism to be used. If you only
 * want to allow D-Bus connections with the `EXTERNAL` mechanism,
 * which makes use of credentials passing and is the recommended
 * mechanism for modern Unix platforms such as Linux and the BSD family,
 * you would use a signal handler like this:
 * 
 * |[<!-- language="C" -->
 * static gboolean
 * on_allow_mechanism (GDBusAuthObserver *observer,
 * const gchar       *mechanism,
 * gpointer           user_data)
 * {
 * if (g_strcmp0 (mechanism, "EXTERNAL") == 0)
 * {
 * return TRUE;
 * }
 * 
 * return FALSE;
 * }
 * ]|
 * 
 * ## Controlling Authorization # {#auth-observer}
 * 
 * By default, a #GDBusServer or server-side #GDBusConnection will accept
 * connections from any successfully authenticated user (but not from
 * anonymous connections using the `ANONYMOUS` mechanism). If you only
 * want to allow D-Bus connections from processes owned by the same uid
 * as the server, since GLib 2.68, you should use the
 * %G_DBUS_SERVER_FLAGS_AUTHENTICATION_REQUIRE_SAME_USER flag. It’s equivalent
 * to the following signal handler:
 * 
 * |[<!-- 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
