AI# samba-tool drs replicate ai svdcp 'CN=Configuration,DC=tls,DC=msk,DC=ru' -d 10

gives some wire traces (or looks like), it ends up like the remote is returning
WERR_FILE_NOT_FOUND. And I don't see this error on the remote, all what I see
remote reporting on the logs is WERR_OK.

However, the other way it works fine:

AI# samba-tool drs replicate svdcp ai 'CN=Configuration,DC=tls,DC=msk,DC=ru'
Replicate from ai to svdcp was successful.


It is even the same when run on SVDCP:

SVDCP# samba-tool drs replicate ai svdcp 'CN=Configuration,DC=tls,DC=msk,DC=ru'
ERROR(<class 'samba.drs_utils.drsException'>): DsReplicaSync failed - drsException: DsReplicaSync failed (2, 'WERR_FILE_NOT_FOUND')
   File "/usr/lib/python3/dist-packages/samba/netcmd/drs.py", line 570, in run
     drs_utils.sendDsReplicaSync(server_bind, server_bind_handle, source_dsa_guid, NC, req_options)
   File "/usr/lib/python3/dist-packages/samba/drs_utils.py", line 92, in sendDsReplicaSync
     raise drsException("DsReplicaSync failed %s" % estr)

SVDCP# samba-tool drs replicate svdcp ai 'CN=Configuration,DC=tls,DC=msk,DC=ru'
Replicate from ai to svdcp was successful.


Who is returning FILE_NOT_FOUND and for what file?

Thank you!
