The point was a simple change that looks like it could satisfy
most of not all of the current users.

I am trying to keep up. I see he sent his 2 minutes before I sent mine.
I also responded to his, as it looks it it would work with Kerberos.

I am saying the the token issuer/mapping service could be introduces
as a standard service of AFS, and could even use gss mech selection.

I am also saying that a lot of the overhead associated with supporting
arbitrary authentication methods can be moved to the token issuer/mapping
service that is only done once per token, rather then being spread
through all of the AFS services and client kernel. AFS can continue
to use the K5 2b tokens internally no mater how they where derived.
