The lsa.umich.edu AFS cell performed the migration this past Saturday,
going directly from AFS 3.4a to MIT Kerberos 5 version 1.2.1 (we'll be
upgrading to 1.2.2 shortly, however).  Len Smith from our group did all
the work on this and he has submitted the changes back to Ken for
inclusion in future versions of the migration kit.

The group that's responsible for the umich.edu cell made changes
available to us that permit the Windows clients to authenticate
properly.  Hopefully they'll make their changes available to the
OpenAFS community.  Here's a hint:  we found that authentication
of the Windows client only failed miserably if you did not specify
a lifetime for the token.  If you authenticate via the command line
rather than the GUI and specify the "-lifetime" flag, you can obtain
tokens which are usable for up to 10 hours.
