Hi Dave,

Currently running 2.4.44 with n-way multi-master setup with rfc2307 schema.

You need to upgrade, 2.4.44 is about 4.5 years old and numerous significant bugs have been fixed with replication since then. It's absolutely unsafe to use 2.4.44 for MPR (also, I'm going to assume you're correctly using delta-syncrepl). 2.4.51 is the current release, change log is here:

https://www.openldap.org/software/release/changes.html

We have tested rfc2307bis before on our lab environment with no issues but never deployed to production.

Some of the benefits I remember about this test is the cool features like "reverse group membership" and "referential integrity" which are not possible with rfc2307.

I'm not sure what you mean by "reverse group membership", can you expand?

I'm not sure what you mean by "referential integrity" in relation to this schema, can you expand? (I.e., referential integrity is usually controlled by the refint overlay, and really has little to do with any specific schema configuration)

My question is two part: • Is switching to rfc2307bis recommended?

If it works with the applications you use, I suppose? Some applications don't support it.

Better performance?

Not clear to me how there is anything related to performance between the two.

• Any issues with n-way multimaster replication?

Not clear to me how this would affect MPR replication.
