Our site has Kerberos V working in conjunction with AFS with no problem.  The
following steps should suffice:

1) Get and install MIT's Kerberos 5 distribution (our installation is based on
the beta 2 distribution, since that's what our OpenV*Secure product is based
on, but I see no reason why beta 4 wouldn't work just as well).  Make sure to
enable Kerberos 4 compatibility when compiling Kerberos 5.

2) Install the krb524 package that Barry Jaspan wrote.  It's included in
recent MIT Kerberos 5 distributions, although it isn't compiled by default. 
Basically, it provides a daemon that resides on the Kerberos server and
accepts requests to convert V5 tickets into V4 tickets, and a k524init client
which users run to produce a V4 ticket file from their V5 ticket file.

3) Install the aklog program distributed by MIT Athena.  One version of it is
available in /afs/athena.mit.edu/astaff/project/afsdev/src/athena/aklog,
although I'm not sure that's the most up-to-date version.  This program allows
you to authenticate to an AFS cell using an existing Kerberos V4 ticket file.

I believe Marc Horowitz is working on a version of aklog which uses the krb524
calls directly, so that it's possible to aklog directly from a V5 ticket file,
but I don't think he's done with it enough to distribute it yet (if he is,
he'll probably speak up :-).
