I converted my database on A to the new format. Then I set up a new clean instance on B and tried to set up replication. The error log on B gave me some errors about entries without parents. So I decided to export my whole data (userRoot) on A into an ldif, set up a new clean instance on A and B, import the data on A and set up replication using the mmr script again. And again I got the error message: "failed to create replica ruv tombstone entry (dc=domain,dc=local); LDAP error - 68" And the initial copy is not complete! Replication info is stored below netscapeRoot that I did not ex- or import, so this cannot be the problem this time, right? I don't think, the error logs are helpful but here they are for completeness: --- errors on A --- 389-Directory/1.2.6 B2010.253.730 a.domain.local:636 (/usr/ldap/etc/dirsrv/slapd-a) [10/Sep/2010:17:59:34 +0200] - 389-Directory/1.2.6 B2010.253.730 starting up [10/Sep/2010:17:59:35 +0200] - slapd started.
