The smb.conf used by the server
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.
