[Samba] winbind still asks for password

[Brent Ross (Edm)]

I am trying to setup a FreeBSD 4.7 Samba 2.2.6 server for W2K clients using
winbind. Everything appears to be working but when I try to connect to the
samba share, I am prompted for a password and no valid password will allow
me to connect. I configured samba using --with-winbind and
--with-winbind-auth-challenge, and followed "Unified logons bewteen NT and
Unix using winbind". Joined the samba server to my NT domain successfully.

wbinfo -t returns "Secret is good"
wbinfo -u returns a list of all my domain users
wbinfo -g returns a list of all domain groups
wbinfo -a mydomain+myuser%mypassword returns success for both plaintext and
challenge/response

Do I need to use PAM if I am only trying to access a samba share and all of
the above work?
If I need to use PAM what config files do I create in the pam.d folder?
smbd.conf, or samba.conf etc.

Thanks in advance.
