Maybe I didn't pose the question very well.
My Proxy Server is configured as a Syncrepl provider. The only difference to a "standard" Syncrepl Configuration is that the data isn't held local on the provider in a database but in a "database ldap".
And this configuration does work.

That means:
Syncrepl should take place between my consumer and the provider (which is itself configured as a proxy). The ldap-server which is working as the database backend of my proxy shouldn't need to understand anything about syncrepl. Correct? If yes - why does an OpenLDAP running as backend work but another ldap server (domino) doesn't?

I've included the 3 relevant slapd.conf files.I would really appreciate some additional input. It's frustrating because it does work...
as long as vm04 is an openldap server and not domino. But from everything I've read, and from my tests, I don't understand why it matters what is behind vm04? It's just an ldap server.

Thank you very much for your support.
Kind Regards
Bonnie

They support their own kind of replication, which is normally already configured,
hence why it appears you don't need to enable anything.

This won't work. Read more about how Syncrepl works at:

http://www.openldap.org/doc/admin24/replication.html#LDAP%20Sync%20Replication

You can only use Syncrepl against a Syncrepl provider.

Also search the mailing list archives for numerous discussion of Active Directory
replication with OpenLDAP.

Thanks,
