thanks for the verry fast answer.
Regarding your question: In my special case i have all the accounts and the passwords in OpenLDAP. The user can change the password on a website and with his windows-client (today with smb-ldap). There are some more applications auhtenticating is against the OpenLDAP-uid/userPassword -Attributes.
O.k. if forgot, because of Clients 389 for samba-ldap must be. But now here comes up some more questions:
Question1: Do i have a chance (and if yes how) to extend the samba's ldap-schema with additional attributes (some private objectclasses) or can i forward request for unknown attributes to samba to another ldap-server ?
Or: if there is no client is authenticating against this server - (only via CDO wich is using RPC) - can i than map samba-ldap on another port allthough the main samba4 is on 389 ?
Or: can i implement your msrpc on another server without running smbd4 ?
You spoke about a test backing parts samba4-ldap to tdb or another ldap. Do you have some more informations about this procedure ?
why do you replay the ldap-base below every object again and again ? For example:
->i saw that with Softerras LDAP-Admin
Hope you'll find some more minutes to answer this questions
Thanks in advanced

Specifically against OpenLDAP, or against an LDAP server in general?

This question means many different things, depending on what you care
about. Firstly, Samba4 includes a backend which allows it to back on to
either a tdb, or an LDAP server. We demonstrate this in some of our
tests (by backing an LDAP server on a tdb, then backing the rest of
Samba4 to that LDAP server).
However, the implementor wishing to back Samba4 onto OpenLDAP (or any
other LDAP server) has to first make that server use the AD schema, and
accept queries that assume that layout. Either that, or implement
(somewhere) a mapping.
Frankly this is hard - particularly for a 'perfect' mapping. I hope we
might get a 'Samba3 migration' mapping, with major limitations, but even
that will be hard.
More reasonable is to have OpenLDAP load an AD-compatible schema, but
that often removes the reason people wanted to use OpenLDAP.

If Samba is an domain controller using the AD logon protocols, then it
must listen to the LDAP port (client requirement).

Not really, but those interested in testing early SVN snapshots of
Samba4 can work with us either on this list, or #samba-technical on
