Description Christina Scheinig

2021-06-24 13:34:11 CEST

Cause:
A Windows-Server with the name index2 was joined into the daomain and after a long time renamed to pdfscan (the hostname was changed on the server).

These is the last reject, which was still present. The hole sync ping pong is in the  attached file.

ALREADY_EXISTS: {'info': 'Entry DC=pdfscan,DC=schein.ig,CN=MicrosoftDNS,DC=DomainDnsZones,DC=schein,DC=ig already exists', 'desc': 'Already exists'}

I could remove the reject, because both data was consistent in samba and ldap.
