I did mean, who created/own's the object in AD-DB and yes, 
ACL is one to look at.

On the push full ad.. 
samba-tool drs replicate --help   ;-) 

  --full-sync           resync all objects
  -d 10 	DEBUGLEVEL 

Look the server that is correct, and use above to resync all from good to bad server.

You also do know that older objects in AD, might and do have wrong timestamps. 
So beware if you use scaveging..  (im slowly.. Deleteing and recreating these objects) 
We inherreted this from below samba 4.7 is i recall right.

I hoped above helped. 

> Thanks.
