We have the following problem.

In our environment we joined a XP 64bit to the Novell-Domain.
But there is an issue with authentication. The login works only
for users with usernames which has more than six characters.

Users with six or less character usernames allways get an RPC-error
while login.

32bit-clients (XP and W2K) make no problem.

Does anybody know the reason for such a behaviour?
