/** AuthObserver - An object used for authenticating connections.
 * The AuthObserver type provides a mechanism for participating in how a
 * Server (or a Connection) authenticates remote peers.  Simply
 * instantiate an AuthObserver and connect to the signals you are
 * interested in. Note that new signals may be added in the future.
 *
 * 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:
 * @code
 * bool on_authorize_authenticated_peer(
 *   const Glib::RefPtr<const Gio::IOStream>&,
 *   const Glib::RefPtr<const Gio::Credentials>& credentials)
 * {
 *   bool authorized = false;
 *
 *   if (credentials)
 *   {
 *     Glib::RefPtr<Gio::Credentials> own_credentials = Gio::Credentials::create();
 *     try
 *     {
 *       if (credentials->is_same_user(own_credentials))
 *         authorized = true;
 *     }
 *     catch (const Gio::Error& ex)
 *     {
 *       std::cerr << "Gio::Error: " << ex.what() << std::endl;
 *     }
 *   }
 *
 *   return authorized;
 * }
 * @endcode
