The credential/token would be fine if we wanted to ask the fileserver for=20
the access rights
every time, but we don't. We want to cache them. The cache needs a key.=20
Right now, the key is the pag number (which is at least 0x41000000) if=20
there is a pag, and the uid if not.

We could store a cache key in the keyring, but that would in fact be=20
providing a "pag" concept that does not use groups. (which is fine, but it=20
would have eliminated PAGs).
