Presumably, you're trying to avoid a proper setup: http://wiki.samba.org/index.php/Replicated_Failover_Domain_Controller_and_file_server_using_LDAP If you already have LDAP authentication and NSS set up, and you don't want to add Samba related attributes to your directory, you'd need to disable "encrypt passwords" in smb.conf and modify the Windows registry so that it sends your passwords in plain text: http://www.encs.concordia.ca/helpdesk/howto/plain_password.html Needless to say, the security of this configuration is awful, but not worse than if you're using OpenLDAP without SSL.
