Thanks Rowland,

you're absolutely right - my bad. s/view/few/
that's what happens when you constantly switch between english and 
german and then write emails late at night ...

I didn't know about the tombstone expunge command yet, so thanks for the 
hint.

samba-tool domain tombstones expunge --tombstone-lifetime=0

removed 10 objects.

Trying to run dbcheck again

samba-tool dbcheck --cross-ncs

now fails due to entries from the previous main dc 
(CN=NAS2,CN=Servers,CN=Default-First-Site-Name,CN=Sites,CN=Configuration,DC=company,DC=intra) 
which should no longer exist since nas2 had been demoted via samba-tool 
~2 years ago.

Do you have also a tip how to remove these orphaned entries?
