My vote is for Multi-master. It does not support delta-syncrepl (and is 
therefore a bit inefficient) but I'm sure it will in the future.

For a geographically dispersed implementation,  multi-master makes 
sense. Master-slave has a single point of failure although you could 
alleviate this by syncing different parts of the tree differently but 
that would be very difficult to set up in some generalised fashion.

Mathieu's Debian port uses  a master-slave delta syncrepl although I am 
still confused by his setup and unable to get it to work. I've paused 
that until I can rtfm some more and grok openldap better.
