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.

Quanah
