I take it that the DCs real name is 'magneto' (HINT: if you are going
to sanitize things, please be consistent)

If you run 'smbclient -L adfs02.int.becit.de -U brokenuser@int.domain'
on 'adfs02', does this work

Does 'getent passwd brokenuser' produce any output when run on 'adfs02'

Have you tried changing the password again ?
