Attaching what I think is relevant.

I think this is a bug caused by the ordering of the various suffixes and has been fixed in the lkatest SAMBA_3) cvs (for 3.0.1). Try setting the ldap suffix first: ldap suffix = dc=os,dc=is ldap user suffix = ou=People ldap group suffix = ou=Group ldap machine suffix = ou=People And please test the current 3.0 cvs tree as well. Marking this one as fixed. If it still exists in the current SAMBA_3_0 cvs code, please reopen the bug report. Thanks.
sorry for the same, cleaning up the database to prevent unecessary reopens of bugs.
