provider/consumer: entries have identical CSN



hi to everyone

I get a strange replication problem. After i didn't find a solution
somewhere on internet i decided to post to this mailing-list. Probably
i should describe my system settings. Both consumer and provider are
running on suse 12.1. And i got the errors with openldap version
2.4.26-3.1.3. Since it is a good
behavior i red somewhere on this email-list, i compiled the latest
openldap v2.4.34 and could unfortunately reproduce the same error.

The Problem is that the consumer does not replicate all objects. The
loglevel on the consumer is

loglevel stats sync

This is the partial output of the /var/log/messages

On the consumer side is all same except the syncrepl directive

Any Ideas? I am glad for every help.
