They are not separate concepts. You can either set up multi-master using standard syncrepl, or multi-master using delta-syncrepl. Just as you can set up a master as using syncrepl, or a master as using delta-syncrepl.Maybe it's that fact that it is Friday or that I've been starring at this all day, I'm just not seeing it.
When you set up your ldap servers, you choose how you want them to be configured. You can either configure the master to keep an accesslog DB that any replicas (including additional MMR nodes) will use for their primary method of doing replication, or you don't do that. If you do do that, then you are using delta-syncrepl. If you don't, then you aren't.
