I favour the admin guide, given the prevalence of misinformation out there:
http://www.openldap.org/doc/admin24/replication.html#Delta-syncrepl
It also discusses which man pages cover this.
Thank you for that, I've already looked at that and I'm a little confused on the process.
What's the best order? MultiMaster then Delta-syncrepl? Or is there a way to combine them both as you setup each master?
As we grow, I know I'm going to need to add more masters to each datacentre.
