samba - Jan 2002 - Trouble mapping shares using domain authentication with a Win2K P DC

I'm having problems with domain security.  I've pared down my smb.conf
to
the minimum, and have successfully joined the Windows 2000 domain.  I can
map the temp share as the guest account.  When I try and map the home share
as a regular user, I see the following errors in my log.smbd file:

My smb.conf is below:

# Global parameters
[global]
        workgroup = DOM
        netbios name = UNIX-NT-TST
        interfaces = 10.0.25.36/255.255.255.0
        security = DOMAIN
        encrypt passwords = Yes
        password server = *
        username map = /var/opt/samba/lib/users.map
        os level = 14
        wins server = 192.168.5.200
        hosts deny = ALL EXCEPT 10.0. 127.0.0.1
        mangled names = No

[homes]
        path = /home/users/%g/%u
        valid users = bver17
        read only = No
        browseable = No

[temp]
        path = /tmp
        guest ok = Yes

The nt username to unix username mapping works correctly (ie: the unixid ntid is
correct).
