Netscape / 389 Multi-Master

[Jim Tyrrell]

Hi,

I have an old Netscape 6.0 setup which consists of 3 Masters in a 
multi-master setup which replicate down to various hubs and consumers.

I was planning on building an exact replacement with 389 consisting of 3 
Multi Masters and the various hubs etc and then settting up one of the 
389 masters to replicate back and forth with one of the Netscape 
masters.  The thinking being that having just one path between Netscape 
and 389 would keep it simple and make it easy to track changes.

Now I read the limit for Multi-Master is 4 servers.  In the above does 
that class as 6 Masters, or is the limit per server in which case each 
server only talks to 2 other Masters, apart from the 389->Netscape 
gateway Masters which would talk to 3 other Masters?

I dont need to have every Master replicate to every other Master do I?  
This is just while we migrate from ancient Netscape servers to 389, one 
complete the Netscapes will be turned off and the replication agreements 
removed on the 389 servers.

Thanks.

Jim.

There really isn't a limit.  The limit was only for the old Red Hat 
Directory Server, and only so far as customer support goes.  The only 
real hard limit is 65534 masters.
