Currently, we always push the supplemental groups in the users  
additional group list - so even when keyring based PAGs are in use,  
you should see the additional entries.

Indeed. One option (and this is a shot in the dark) is that it's a PAM  
issue. If Ubuntu have started using pam_keyinit, then it's vital that  
this is run before any AFS PAM module. Otherwise, pam_keyinit will  
happily replace AFS's keyring with its own.
