Hi Quanah,

Why is RefreshOnly ill-advised?  That is the recommendation in the docs
(very timely as I just set this up again myself).

re:  http://www.openldap.org/doc/admin24/replication.html

The admin guide has examples, not recommendations.  In any case, I fully
intend to change those examples to be refreshAndPersist so people stop
defaulting to refreshOnly.  It is not always reliable, and your
significantly delay your replication by using it.

Of course, it may be the only thing that works reliably if you have a
firewall that silently kills old connections.

The examples should stand as-is. We cannot predict what environment it's
going to be deployed in. It's up to administrators to use their brains
and know these details of their network.

I think at the least we should document both. Virtually everyone takes the admin guide verbatim without comprehending what it is they are doing. Giving them two options would hopefully at least make them have to consider why there are multiple options.
