And I bet they also said that running Microsoft products has a lower Total Cost of Ownership than anything else too. 

Yeah it's some of the guys that believe in all that.

But as I'm able to dismiss all his claims, with all I can't.

AD works in a multi-master environment, OpenLDAP doesn't.

We don't really need a multi-master environment, but can a claim that a multimaster environment is much more superior over master-slaves model in terms of preformance - can this claim be true?

As I studied the multimaster AD replication a bit:

and for me, it seems that it can be more efficient, as it would need at least one connection less.
On the other hand, there seems to be much overhead concerned with additional data that goes around to keep this multimaster state in sync.
