It turns out that with the mentioned server, Kerberos doesn't work with
Windows clients, either. Instead I can see (in wireshark) the Win
clients falling back to NTLM authentication (or using it right away).
That explains a lot. Sorry for the noise. (I'm currently looking for a
switch in XP to force it to use Kerberos for testing purposes, but so
far I found none).
