OK thank you for your answser. I am a bit confused with nss, pam and the 
Samba authentication mechanism...

Actually I would like to add filters for authentication of users with 
Samba and LDAP :

With our production servers I use the 'ldap filter = (MY_FILTERs)' 
option in smb.conf (samba-3.0.11) but this option has been removed in 
the recent releases. Now I want to upgrade samba and I would like to use 
the same filters with the samba-3.0.26a.

I read that it was in the ldap.conf file but I don't know how to use it...

If anyone can give me a clue...
