Hi,I would like to know if 389 DS closely follow this RFC specs http://tools.ietf.org/html/rfc3384 for multi-master replication support
For what reason are you asking? Note that there are no directory servers that implement complete support for RFC 3384.
since then it is not included in the lists of standards here http://directory.fedoraproject.org/wiki/Documentation. If yes, what requirements are already supported and what are not?
That would be fine for now just as long as this RFC is the reference basis for multi-master replication
Yes Rich, multi-master replication in 389 DS only.
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.
because I'll be using it as a supporting reference document for my ongoing research on LDAP multi-master replication.
Cross vendor multi-master replication is not part of the scope of my implementation for now but probably in the future I might tackle this so, thanks in advance in giving me hints/info on other implementations LDUP support.
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.
Any idea what makes any directory server implementations don't have complete support on this RFC?
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.
Are there any requirements conflicting or not appropriate to architectural design of any implementations?
Alright don't worry, I'll observe how the multi-master replication behavior goes and cross check the RFC.
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.
Ok, got it and thanks for answering my questions. Really appreciate it and now I know the story behind.
Thanks a lot!
Thanks a lot!Best regards,Archimedes
