[Samba] Winbind problem

[Pablo Marques]

Hi:

I am trying to use winbind and users from a Windows domain in a Samba
server on a RedHat 7.2 machine.
I added the machine to the NT Domain with no problems.
But I see a very odd behavior:

#wbinfo -t
Secret is good

#wbinfo -u
gives me the correct domain user list

#wbinfo -g
gives me the correct domain group list

#wbinfo -a MYDOMAIN+user%password
plaintext password authentication succeeded
challenge/response password authentication failed
Could not authenticate user MYDOMAIN+user%password with
challenge/response

#getent passwd
gives me the local users + domain users
#getent group
gives me the right local group + domain groups

So far so good
Now:

#su MYDOMAIN+user
su: user MYDOMAIN+user does not exist

#chown MYDOMAIN+user /tmp/a
chown: 'MYDOMAIN+user' : invalid user

Am I missing something here???????????

My configuration:
RedHat 7.2 + SGI XFS + samba-2.2.3-20020202
Windows NT 4.0 PDC

nsswitch.conf entries:

passwd:     files winbind
shadow:     files
group:      files winbind

Winbind entries in smb.conf:
[global]
        workgroup = MYDOMAIN
        netbios name = Server1
       interfaces = eth0
        security = DOMAIN
        encrypt passwords = Yes
        password server = pdc, bdc
        pam password change = Yes
        log level = 3
        log file = /var/log/samba/%m.log

        printcap name = cups
       preferred master = auto

        domain master = False
        dns proxy = No

        winbind uid = 10000-20000
        winbind gid = 10000-20000
        winbind cache time = 86400
        winbind separator = +
        printer admin = @"MYDOMAIN+Domain Admins"
        printing = cups

etc....
