connecting linux box to windows 2000 domain

[Derek Doucette]

I am having some problems connecting my linux box to a win2k domain.  After running the command smbpasswd: -j <NT_DOMAIN> -r <NT_PDC> my machine gets added to the system, and can be seen by computers on the network, however in order to authenticate, I still need to use my linux box account.  

In the smbusers I have added my 2000 username to my linux entry.  When I ran the command to join the domain, I was told that there would be a <domain>.<sambaname>.mac file.  I have no such file or any .mac file present.  In my smb.conf file the global section is as follows:

[global]
        ;smb passwd file = /etc/samba/smbpasswd
        path = /home
        dns proxy = no 
        encrypt passwords = yes
        socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
        valid users = derek, mike, ddoucette
        wide links = no
;       printcap name = /etc/printcap
        max log size = 0
        server string = Alpha_linux Samba Server
        comment = alpha_linux home directory
        log file = /var/log/samba/%m.log

        ;testing for NT Domain
        netbios name = ALPHA_LINUX
        workgroup = SERVERS
        password server = *
        security = domain
        add user script = /usr/sbin/useradd %u -g smbusers
        delete user script = /usr/sbin/userdel %u       
        local master = no
        os level = 33
        wins support = no
        wins server = *.*.*.*
        hosts allow = 10. 127.

Any ideas why I cannot authenticate with my windows user info or how to get a .mac file?  This is my first shot as samba, so it should be something easy that I overlooked.

Thanks, 
Derek
