server redundancy setup

[Rex Roof <rex@wccnet.edu>]

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?
