Samba 2.2.2 got parinoid about what characters can be in usernames.  If
you can't change the username, you might consider modifying the list of
allowed characters - in smbd/reply.c:reply_sesssetup_and_X(), the
'alpha_strcpy' line.

Also see
for the similar problem with different characters.  

I do hope to be able to remove this check in Samba 3.0, but we have to
be very careful first.
