Description Elias 2024-02-03 00:04:33 UTC 
hi,

When executing the replication command between two Domain Controllers (DCs), I check the log of the receiving DC. Even though the command response indicates that the replication was successful, the following error occurs.

root@dc1:/etc/samba# samba-tool drs replicate dc002 dc1 DC=campus,DC=sertao,DC=ifrs,DC=edu,DC=br --full-sync
Replicate from dc1 to dc002 was successful


root@dc002:~# tail -f /var/log/samba/log.samba

How can I get a full backtrace to help you?

When running the command "samba-tool dbcheck --cross-ncs --reset-well-known-acls --fix --yes" the error also appears in the logs:
