I thought perhaps Windows would deny a member of 'guests' to be
authenticated with a ticket. I don't use groups for the kerberos
principals but only for the 'test-user' account on my windows machine
that I map the principal to.

My ASN.1 reading cababilities are very limited but the tickets look just
fine to me. Especially since exactly the same tickets are accepted by
the GSSAPI version of the service implementation... Is there something
about this SPN thing? Actually I'm doing somewhat strange here, since I
made my client and service apps talk to my kerberos test realm, with my
machine being in a different NT domain. As I mentioned before, just a
proof of concept.

Best Regards,
Daniel.
