Re: server redundancy setup

I'm migrating our existing openLDAP 2.3 servers into a new setup running openLDAP 2.4.

I will eventually have 4 or 5 servers, hopefully all having the same synchronized data, and all accepting writes, if need be.

Can anyone suggest a configuration where I have 4 servers, all keeping themselves in sync, and all accepting writes?

Can multimaster replication work with more than two servers? Is that the right solution here?

Yes, MMR can be achieved with more than 2 servers, theoretically the number of hosts is limited by the number of available network I/O's. Personally I am not in favour of MMR, I would prefer syncrepl and chaining referrals, if possible.
