I'd be shocked if umich didn't have 100,000 user ids in their AFS cell.

they have I think 35,000 active students, all of whom get an AFS identity
& home directory, something like 10k or 15k staff & faculty, and god knows
how many years of crufty users who haven't been deleted.

How many are actually *active* users is another question.  I'm sure it's
a fraction of these people.  Maybe as many as 20,000 although that could
be way off.  I'd be shocked if it were fewer than 5,000.

The windows client has been under active development for the last year
and a half or so and has vastly improved.

This is just a vague recollection, but I think you can do windows roaming
profiles with AFS as the file store.  You still need an AD or samba to
manage the windows information, though.

You can have AD backend to the same kerberos 5 database as afs uses.  I
think you can even use AD as AFS's kerberos 5 database.
