Oki, the admin have now create a keytab using:

----- s n i p -----
ktpass -princ afs/<cell>@<REALM> -mapuser <city>_afs -pass * -crypto DES-CBC-MD5 -out c:\temp\unixkeytab
Targeting domain controller: <domaincontroller>
Successfully mapped afs/<cell> to <city>_afs.
Type the password for afs/<cell>:
Type the password again to confirm:
WARNING: pType and account type do not match. This might cause  problems.
Key created.
Output keytab to c:\temp\unixkeytab:
Keytab version: 0x502
keysize 75 afs/<cell>@<REALM> ptype 0
(KRB5_NT_UNKNOWN) vno 3 etype 0x3 (DES-CBC-MD5) keylength 8 (0xe9801968ba2aada4) 
----- s n i p -----

Unfortunatly this gives me other problems:

The only reference I found about this problem was 
http://comments.gmane.org/gmane.comp.file-systems.openafs.general/19094
and I tried the same trick with ktutil but it did no change:

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

I've inquired what version of ktpass.exe/os the're running
on the AD, but haven't got a reply yet (probably lunch :)...


Just if it matters, I compared the keyfiles as well.

They ARE different, but since neither work... ? Did I miss restarting
something?  I'we been waiting for more than the 'AD sync time' so it
can't be that...

And the time is syncronized with ntpdate from the same NTPd as
the AD once every hour...


PS. I just noticed the timestamp on 'unixkeytab'... Might be nothing,
    but...
