In the AFS case, you need to add groups to the process context (and place
the Kerberos ticket into the kernel in that process context).

In the Kerberos case, you need to write out your credentials to a file,
and then set an environment variable so the other applications can find
the credentials.

Well, I'll be interested in seeing your redesign ... but I'm not holding
my breath that they're going to end up being simpler (to solve the problems
that you need to solve, I'm not sure how much simpler you could make them).
