Hi list we have a samba 3.6.6 pdc on debian 6.0.6 with passdb backend = ldapsam. Our workgroup is ARCD. The winbind-idmap log says: [2012/10/10 13:04:48.771095, 1] winbindd/idmap.c:288(idmap_init_named_domain) no backend defined for idmap config ARCD Extracts from smb.conf: workgroup = ARCD ldap idmap suffix = ou=idmaps idmap config * : range = 12000 - 30000 The manpage says that tdb is the default backend and that * catches all domain names. Why do I get the above log message? Is there still something wrong? Thanks for your help Sebastian
