Thank you for clarification, is it possible to share what are the missing attributes?
There are a number of them (such as entryUUID, entryCSN, etc). Regardless, for replication to work, the operational attr values must be the same across servers. This is generally why if you're bringing up replication in an environment where you already have an existing DB, you slapcat the DB off your "golden" master, and then use slapadd to import it to the other servers.
