You should get rid of the "winbind uid" and "winbind gid" parameters as
they have been superceded by "idmap uid" and "idmap gid".
Did you install the libnss_winbind.so module you built (it's in the
~samba/sources/nsswitch directory) as /lib/nss_winbind.so and link it to
the appropriate version name?
Have you modified in /etc/nsswitch.conf the following:
passwd: files winbind
group: files winbind
Do you obtain correct domain account information from:
getent passwd
and
getent group
You will need to install the LDAP admin password into your Samba
secrets.tdb file. The command that does that is:
smbpasswd -w 'secret_password'
PAM provides authentication, NSS (name service switch) does Identity
resolution. It is the instrument that will permit the LDAP database to be
populated via winbind.
I hope this helps.

John T.
