Howard, does this new replication feature in OpenLDAP work in both directions?
Not at the moment. It only allows OpenLDAP to replicate from DSEE. It probably
difficult to write an overlay to generate a compatible changelog, for going the other
390ds also impelments SyncRepl as a plugin, so this could also be an
option to try, but it would still provide only the direction 389ds
For the other direction 389ds would have to offer some "pull
replication" feature, which doesn't exist.
A further problem would be in synchronizing updates from several
sources, 389ds uses CSNs and RUVs, openldap also has CSN, which are a
similar concept, but not directly compatible.
So, even if there are approaches to do it, I think we are not there.
The commit is here, includes the code and a test script that sets up the DS and
polls it for changes. We'll probably add persistent search on top of this soon as
