back-ndb is for mysql?
so you're suggesting that I mirror the data using a mysql cluster and just build multiple frontend servers to run slapd, all connecting to the same mysql backend database?

How are we supposed to be setting up OpenLDAP servers so that we can have failover? I want to have a half-dozen OpenLDAP machines and have any one of them accept writes and not be relying on any one of them to be up for writes to occur.

Well, welcome to the world of distributed systems. You probably want back-ndb once a few of its indexing quirks have been worked out, since that uses multiple slapd instances to frontend a single mysql cluster database. You could of course, use mirror mode and chaining as an alternative. But in any sort of distributed system like MMR, changes get delayed.
