How to setup trust between 2003 SP1/R2 and MIT 1.4.3 ?

Three further observations
=> 1) User WINDOWS2003\markus-a CAN NOT connect with putty from Win XP to
opensuse.suse.home (no port 88 traffic)
I can connect as user WINDOWS2003\markus-a with putty 0.58 with
GSSAPI (e.g. MIT libraries) from Win XP to
opensuse.suse.home
=> 10) User markus at SUSE.HOME CAN NOT connect with Firefox from OpenSuse to
http://w2k3.windows2003.home. I get a KRB5KDC_ERR_ETYPE_NOSUPP
error (see below capture of AS-REQ,
AS-REP, TGS-REQ, TGS-REP)
It works when I change the encryption types in krb5.conf to only
des on OpenSuse.
and I CAN NOT login to the Win XP box as markus from domain SUSE.HOME. I
tried ksetup /mapuser * * with no suceess.
Any idea what I need to change ?
Thank you
Markus
