Ok, I'm going to look into this.

I see.  I think nscd would achieve the same effect...

Also, while I'm hacking on this, two more questions:

 1. Does it make sense to map AFS group ids (with the sign reversed)
    onto GIDs?

 2. Previous suggestions about shells involved putting users into
    groups named after shells, such as

      pts add adam shell:bash

    But it seems that this wouldn't allow users to manage their own
    shells since shell:bash would belong to some administrative user.
    What about an alternative, where users would create a group

      pts cg adam:shell.bash

Davor Ocelic also had a neat suggestion about giving human-readable
names to PAG groups.
