You can set the effective uid of the root process to the users process to connect to user's session bus and then reset it and gain back the privilege. > With polkit you currently request something over DBus from a helper and you get a reply back. What you're describing you want is exactly that, except the reply happens a file descriptor. (which as you hint is a native DBus type) Why do you need to register a service in the ioslave? QDBusUnixFileDescriptor object is required to send a file descriptor over dbus. The service must have a method accepting QDBusUnixFileDescriptor as an argument, QtDBus won't create it automatically. KAuth doesn't have any such method thats why the need for a separate service.
