mach ports and the remote uid

While receiving a message on a mach port from a remote process, is it possible to determine the effective user id of the sending process?

What I'm trying to accomplish is:

A server process listens for mach messages from many different processes [which the server has no prior knowledge of], and acts only upon trusted messages. Trusted means the message came from a process running as uid 0.

Thanks,
-Kevin
