[Samba] "Unable to fetch value for secret ..., are we an undetected RODC?"

[Adam Tauno Williams]

Since upgrading S4 DCs I am see the following message in log.samba -

DsCrackNames: Unsupported operation requested: FFFFFFF8DsCrackNames:
Unsupported operation requested: FFFFFFF8Unable to fetch value for
secret BCKUPKEY_13bb48fc-0844-4736-9972-e26453333856, are we an
undetected RODC?

  Unable to fetch value for secret BCKUPKEY_13bb48fc-0844-4736-9972

The message "Unable to fetch value for secret BCKUPKEY_13bb48fc-0844
-4736-9972-e26453333856, are we an undetected RODC?" repeats
frequently.
