Yes, that's the group that tracks the AFS PAG.

Yup.

AFS has always worked this way.  The PAG group can in theory be dropped on
kernels where keyrings are used to track the PAG, although there are
AFS-aware tools that will be confused about the PAG status if that group
is not present.  I think that's being looked at for the next major version
of AFS.

But this isn't a bug in pam-afs-session; indeed, for the current version
of AFS, it would be a bug if it *didn't* add that group.
