samba - Mar 2007 - Groups unknown (but users ok) on members of Samba domain

Originally, I set up a PDC with Debian and Samba 3.0.14a. Users and 
groups (both unix and Samba) are in Openldap.

There are a couple of Samba domain members which get users and groups 
via winbind from my PDC. In order to have consistent user/group ids an 
Ldap Idmap is used by all Samba computers but nothing else comes from 
Ldap directly to any domain member.

Everything worked fine with only a few minor hitches.

wbinfo -u showed users, wbinfo -g showed groups on any domain member.

Now, after upgrading the domain members to Samba 3.0.24 things are still 
ok but when I upgrade to Samba 3.0.24 on the PDC none of the domain 
members (neither Samba nor Windows) is able to list any groups.

wbinfo -g  says "Error looking up domain groups".
wbinfo -u still shows users.

After downgrading Samba on the PDC back to 3.0.14a the problem goes away.


Thanks for any help

Solved:

I had an old version of /etc/ldap/schema/samba.schema.

In Debian this is shipped with package samba-doc and has then to be 
copied manually.

Thanks to Dale for the hint.
