The afs/cell.name service principal only belongs to the standard
"domain users" group, (I think this is standard), and I do not believe
the afs service principal will need to be in any other groups. Thus
the PAC data for the service principal should not be growing. And as
long as it is less then 12k this should not cause a problem,
sound correct? Thanks.
