Hi Quanah,

If want to replicate Production (DC) site with Recovery (DR) site at real time without any time lag which replication,DB and openldap verison would be best to implement.

I've already stated you need to upgrade to the current OpenLDAP release. I do not know how to make that any clearer. Additionally, it would literally defy physics to have instantaneous replication. There will always be some amount of delay.

I would generally recommend the current OpenLDAP release using back-mdb as the database engine and delta-syncrepl using refreshAndPersist.
