On one of your DCs? As in you run Samba for your DCs?

This thread was using Server 2012 R2 as DCs, and that was what my
response was aimed at. I am also using Server 2012 R2 for DCs. In this
case the Administrator is "just a user" seen from the linux boxes.
That Administrator is assigned a root-role in a Samba DC is not a
surprise for me as it then becomes more than external windows user,
but rather has to somewhat resemble the "full access" special internal
role an Administrator has on Windows Domain.

With this misunderstanding out of the way I can see your arguments. I
find it rather confusing that you use arguments for the Samba DC in a
thread for a Server 2012 R2 use case but that might just be me.
