[Samba] winbind and exclamation mark

[Marco Berizzi]

Hello.

I'm having a problem with winbind/samba-2.2.8a on Slackware
linux 9.1 (glibc 2.3.2, kernel 2.4.24, gcc 3.2.3) with a user
account on a Windoze NT 4.0 PDC named !schedule
I always get "Access denied" from the windoze NT 4.0 box and
syslog on samba box reports:

domain_client_validate: unable to validate password
for user _schedule in domain DOMAIN to Domain controller srvnt1.
Error was NT_STATUS_NO_SUCH_USER.

I think the problem is the "!".

Any hints?
