I'm replicating both the config and backend databases between two boxes.
Everything seems fine, but for some reason
when I query them both for the contextCSN, the config database returns only one
while the backend database returns two,
as seen below:
## ldap1 replication config

I checked the documentation, but didn't see anything that clarified this
behavior. I've also checked the logs, and
there are no replication failures in them. So what is the reason for this?
The only difference I can see between the
config and backend is that the backend database has two overlays (autogroup and
syncprov) and the config db has only one
(syncprov), but that may just be an irrelevant coincidence. I would be most
appreciative if somebody could shed some
light on this for me. Thanks!
