[OpenAFS] Openafs new windows clients:authentication with AFS transarc dbservers?

[giovanni bracco]

We run a AFS cell with AFS transarc dbservers and standard kerberos 4.

A colleague working at MIT site [athena.mit.edu] has problems in 
authenticating to AFS  from his windows laptop (XP SP2, OpenAFS 1.3.75) and 
gets the message:
"Cannot resolve network address for KDC in requested realm"
when she tried to get a token from the OpenAFS tray panel.
That sistem is configured also to access the local system athena.mit.edu.

On the contrary on another system with  OpenAFS 1.2.11, (that is not 
configured to access athena.mit.edu ) everything works nicely with our AFS 
cell.

In OpenAFS documentation
http://www.openafs.org/dl/openafs/1.3.76/winnt/afs-install-notes.txt
I have found the following:

....
As of 1.3.65, the OpenAFS client will directly use Kerberos 5 tickets as 
tokens if KFW is installed.  The client requires that all of the AFS Servers 
with which it communicates support the use of Kerberos 5 tickets as tokens 
(aka 2b tokens).
This means that all of the AFS servers must be running OpenAFS release 1.2.8 
or higher.  Transarc servers do not support Kerberos 5 tickets as tokens.
....

and I suppose that this can be the reason fro the problems in the former 
system.

How can we solve the problem: authentification to old AFS transarc dbservers 
from the last version of OpenAFS Windows client?

Thanks

Giovanni
