[Samba] WARNING: no target object found for GUID component link lastKnownParent in deleted object
hi, I have this DC in aws to fulfill the authentication need of our moodle. # samba -V Version 4.17.7-Debian DNS with SAMBA_INTERNAL The replication of the users and groups happens correctly. Some errors in running samba_dnsupdate, but it is ok anyway.
