When you set up your ldap servers, you choose how you want them to be configured. You can either configure the master to keep an accesslog DB that any replicas >(including additional MMR nodes) will use for their primary method of doing replication, or you don't do that. If you do do that, then you are using delta-syncrepl. If >you don't, then you aren't.
Does that help? ;)
I think so.
So then based on the examples here : http://www.openldap.org/doc/admin24/replication.html#Delta-syncrepl
It would be a combination of provider AND consumer on each each server with the N-Way config.
Correct ?
