If this is a direct connection, there's dbus_connection_get_unix_user.

If you're receiving this message through the bus, call the
org.freedesktop.DBus.GetConnectionUnixUser on the bus.  Example Python:

python -c "import dbus;
bus=dbus.SystemBus().get_object('org.freedesktop.DBus',
'/org/freedesktop/DBus'); print dbus.Interface(bus,
'org.freedesktop.DBus').GetConnectionUnixUser(':1.11')"
