Thanks for the answer, but we need write access from all of our instances, so mirror mode isn't a viable solution for us. By definition, only Multi Master will serve this requierements right?
Multi Master require that all the instances are defined into all the instances?
Thanks in advance.

Hi all.
We are implementing a solution with multi master LDAP, we have 11 instances at different locations, and maybe we will grow to 21 or 31 instances before the end of the year, expecting to hold something like 200,000 or 300,000 user entries. What topology would be the best? Right now each server synch to all the other servers, is it possible to configure each server to synch only to a central LDAP? is it convenient?
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
