Yes, I found that eventually.

It only halfway for me. Looking at the MIT Kerberos V KDC logs, i see that 
the win client seems to be getting a ticket:

----- s n i p -----

But I don't get logged in. The login say:

----- s n i p -----
The system could not log you on. Make sure your User name and domain are correct,
then type your password again. Letters in passwords must be typed using the correct
case. Make sure that Caps Lock is not accidentally on.
----- s n i p -----

I'm trying to login with my username (without the realm etc) and

Log on to: <MYREALM.TLD> (Kerberos Realm)



But as the KDC logs show, it seems like the login was successful. Do I have to
have something more (Samba comes to mind)?


Also, the KDC is on the 'Net, but the client is behind a masquerading Linux
firewall (have no problem with auth on a Linux client using LibNSS-LDAP/LibPAM-LDAP
with LibPAM-Krb5 etc).
