If samba was run before setting up the idmap backend parameter then a winbindd_idmap.tdb file would have been created. Simply delete it, it should not be used once the LDAP backend has been configured. - John T. -- John H Terpstra Samba-Team Member Phone: +1 (650) 580-8668 Author: The Official Samba-3 HOWTO Reference Guide, ISBN: 0131453556 Samba-3 by Example, ISBN: 0131472216 Hardening Linux, ISBN: 0072254971 OpenLDAP by Example, ISBN: 0131488732 Other books in production. -- To unsubscribe from this list go to the following URL and read the instructions: http://lists.samba.org/mailman/listinfo/samba
