Then that is not Multi-Master, but normal Provider/Consumer replication.

Depending on your client requirements for writing, you may be better served
using MirrorMode and numerous consumers/slaves with the chaining overlay to push writes
back to the master. This would be simpler for monitoring write propagation.

See the diagram here http://www.openldap.org/doc/admin24/replication.html#MirrorMode
