samba - May 2003 - samba as a domain member server using winbind

hi all

i seem to be having a problem replicating an installation of samba as a
"domain member server" to our NT4 PDC

when i initally installed samba i was able to use the DC's as the
authentication source to allow the windows workstation access to the samba share
via winbind, it all worked well, as documented, i didn't even need to setup
user accounts on the samba box.

now that i'm building the production server, i can't seem to replicate
the success, no matter what i try the samber server keeps returning a username
and password dialog box to the windows users and logs the below error for the
users trying to connect....

I successfully joined the domain by " smbpasswd -j PDC -r PDCNAME -U
Administrator"
(Note: I needed to add the samber server to the domain on the PDC first before I
could join on the samba server)

my smb.conf

the correct libnss_winbind links in /lib

/etc/nssswitch.conf
----------------------------
passwd:     files winbind
shadow:     files
group:      files winbind

only problem is, i don't recall if i needed to setup PAM, if I do can anyone
point me in the right direction, do I need to edit "/etc/pam.d/login"
so the windows users can authenticate and access the share ?

any suggestion would be appreciated.
