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
For example, if you only want to allow D-Bus connections from processes owned by the same uid as the server, you would do this:

GDBusAuthObserver * g_dbus_auth_observer_new            (void);
Creates a new GDBusAuthObserver object.
| Returns : | A GDBusAuthObserver. Free with g_object_unref(). | 
Since 2.26
gboolean g_dbus_auth_observer_authorize_authenticated_peer (GDBusAuthObserver *observer,GIOStream *stream,GCredentials *credentials);
Emits the "authorize-authenticated-peer" signal on observer.
| 
 | A GDBusAuthObserver. | 
| 
 | A GIOStream for the GDBusConnection. | 
| 
 | Credentials received from the peer or NULL. | 
| Returns : | TRUEif the peer should be denied,FALSEotherwise. | 
Since 2.26
"authorize-authenticated-peer" signalgboolean user_function (GDBusAuthObserver *observer, GIOStream *stream, GCredentials *credentials, gpointer user_data) : Run Last
Emitted to check if a peer that is successfully authenticated is authorized.
| 
 | The GDBusAuthObserver emitting the signal. | 
| 
 | A GIOStream for the GDBusConnection. | 
| 
 | Credentials received from the peer or NULL. | 
| 
 | user data set when the signal handler was connected. | 
| Returns : | TRUEif the peer is authorized,FALSEif not. |
