Iam attempting to join a new server (samba-4.15.4 installed in a new
server) to an existing samba AD. But getting the error and the domain join
failed, The error is listed below.

rolled back

ldb_wrap open of secrets.ldb

For Adding additional DC to existing one, execute the below command.

*#samba-tool domain join ktk.com <http://ktk.com> DC -U"KTK\Administrator"
-d4*

Let me know about the solution for this error and join the Additional DC
without error.

Thanks,
