my reading of syncrepl matches your understanding but I'm still using
slurpd so what do I know.
You should know that the philosophy of OpenLDAP software developers is
that if you actually want to run an OpenLDAP server using newer edge
features (and syncrepl is surely one of them), then you should be
building the latest from source and not relying on distribution packages
which exist mostly for providing ldap libraries for other software.
There was a recent discussion about this very topic because
Debian/Ubuntu is using a 2.4 version that is also out of date and very
buggy where syncrepl is concerned. Obviously CentOS is using 2.3.43
which is considered out of date by OpenLDAP software developers.
