## Detailed Description

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:

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;
}

Since glibmm 2.26:

Parameters

  stream | A IOStream for the DBusConnection.
  credentials | Credentials received from the peer or `nullptr`.
