So for some reason, it seems that the version was not passed correctly when the connection between replicas was being established. I guess we will not find out the root cause, given you successfully rebuilt the server. I am still CCing Ludwig and Thierry for reference. </blockquote> Hello, The DS master (or replica) sent a start-replication session with an empty GUID payload (added by ipa plugin). It should happen if you mixed DS and/or IPA version, is it the case ? thanks thierry </body> </html>
