Fedora directory users - Nov 2006 - setting up replication on consumer

Hi All,

I am trying to set up replication to have a read-only consumer getting updates
from a multi-master supplier.  I''ve looked at the online docs and am
using the mmr.pl script as a basis for a modified script to set up a
supplier->consumer agreement.  I think I''m almost there except for
one question.

Before doing the script, I manually added the replica database on the consumer
to see how it works.   I went to the Configuration tab on the console for the
consumer, and selected the database under Replication that I wish to replicate. 
I set it to be ''Dedicated Consumer''.  When I did this in the
console, it does not allow you to set a Replica ID, and it set it automatically
to 65535 when I saved.

In my modified script, I copied the ''config_supplier''
subroutine by duplicating it as config_consumer, and I took out the part where
it sets the nsDS5ReplicaId thinking it must be unnecessary for the consumer. 
When I try to run my script, I get this error on the consumer side because of
removing that part:

failed to add replica entry: missing attribute "nsDS5ReplicaId"
required by object class "nsDS5Replica"

So, I guess I need to add it back in...  Can someone explain how this works and
why the console doesn''t allow you to set it?   Is there some default
value (eg 65535) that should *always* be set (seems unlikely in the case of
multiple replica database objects).

The console is smarter and has additional logic to just hardcode the 
value to be 65535 for read only replicas.  Read only consumers (hubs, 
dedicated consumers) must have the attribute "nsDS5ReplicaId" and must
be set to the value of 65535.
