Hello,

We recently upgraded our Openldap installation to a current version. Our installation consists of 2 servers with several databases, of which a few are replicated in mirror mode. Together with the upgrade process we reconfigured which data gets replicated and which not and modified the databases accordingly.

Now, when we synchronize data between the nodes the intial replication works just fine. But replication of changes afterwards fails and we get these error messages:

Any idea what may have gone wrong here?

The suffix o=lpfroot is in a non-replicated database, the glued sub-suffix ou=Directories,o=lpfroot is in a replicated database. The databases are still bdb as before.
