Multi-master replication in 389?

Cross vendor multi-master replication?  AFAIK, only 
Netscape/iPlanet/Sun/389 derived servers support the LDUP RFCs, and only 
a subset of the LDUP RFCs.  Novell eDir probably supports some of LDUP too.

The LDUP working group never reached a satisfactory conclusion with 
working implementations.  The Netscape implementation was based on early 
work of the LDUP working group, but diverged in some ways, and in other 
ways didn't keep up with later work by the LDUP group.

Well, I suppose I could go through the LDUP RFCs point-by-point to 
figure out where 389 diverges, but that's not really an exercise I care 
to undertake.

If you're asking for a list of all of the places where 389 is in accord 
with the LDUP RFCs, and a list of all of the places where 389 diverges, 
and the reasons why, there is no such list.
