Get the sender's unique connection ID from QDBusContext (message().service()) 
then call GetConnectionUnixUser on the main bus interface (see 
QDBusConnectionInterface for a wrapper, which you can get with 
connection().interface()).

As in:
	QString sender = message().service();
	QDBusReply<uint> uid = connection().interface()->serviceUid(sender);

There's a function on Windows for obtaining the SID, but there's no C++ 
wrapper for it on QDBusConnectionInterface. You'll need to do 
call("GetConnectionCredentials", sender).
