Hi, I currently migrate an existant earlier SAMBA (Version 2.2.9) / OpenLDAP (slapd 2.2.26) configuration to SAMBA (Version 3.0.25b-0.4E.6) / OpenLDAP (slapd 2.4.11). To preserve the compatibility with my schema.v2, my new smb.conf now contains : passdb backend = ldapsam_compat:ldap://w.x.y.z:389 (where w.x.y.z is the ldap server) Simultaneously, for same reason, i kept uncommented the historical section of my samba schema.v3 on my ldap server. I can either ask my domain and ldap server, that's OK I can insert and remove machines in/from my domain, i can authenticate users too, BUT each times i've got the problem with the message : "Your password expires today" when connecting from microsoft windows xp-client. I' ve tried the envisageables solutions, read on this list, but so far without result : # net groupmap list [2010/04/29 10:59:05, 0] param/loadparm.c:map_parameter(2765) Unknown parameter encountered: "maximum password age" [2010/04/29 10:59:05, 0] param/loadparm.c:lp_do_parameter(3505) Ignoring unknown parameter "maximum password age" # pdbedit -P "maximum password age" -C 4294967294 Unknown parameter encountered: "maximum password age" Ignoring unknown parameter "maximum password age" valid account policy, but unable to fetch value! account policy "maximum password age" description: Maximum password age, in seconds (default: -1 => never expire passwords) account policy "maximum password age" value was: 4294967295 valid account policy, but unable to set value! # pdbedit -r -c "[X ]" -u martin Unknown parameter encountered: "maximum password age" Ignoring unknown parameter "maximum password age" Unix username: martin NT username: martin Account Flags: [UX ] ... What is wrong on my configuration? Thanks for helping. Best regards Fran?ois
