In my previous reading it seemed like fractional replication
wasn't
possible in a multi-master environment. Statements like this from the
administrators guide: "Fractional replication can only be done where
the consumer is a read-only replica" are what i'm referring to. Am I
misunderstanding what fractional replication is?
It is now supported in most cases.
Please direct me to statements like
the above in our docs and I will fix them.
Thanks

I suppose this might be a problem if the schema were somehow
different between the two servers, which could happen if you added
the schema via a file and not via LDAP.

memberof should not be replicated - see
http://docs.redhat.com/docs/en-US/Red_Hat_Directory_Server/8.2/html-singl...
there is an Important Note on that page about replicating memberof

I suppose this could be possible if the password policy is
different on the supplier and the consumer
