samba - May 2019 - password server not sending authentication requests to a specified DC

Our goal is to have a particular DC which will be used by our proxy for 
user authentication.

We tried to use only the required DC as a nameserver but that doesn't 
work, queries are still sent to other DCs.

You still haven't said why you must use a particular DC, all DC's are 
equal, so it shouldn't matter which DC you connect to, you should get 
the same info back. That is unless one DC is in the same building and 
another is on the other side of the planet, in which case, you should 
investigate 'sites'.

just one other thing, when replying to a thread, please reply, don't 
make a new post.

This is where it gets difficult, I get the feeling that the original 
DC's are Windows DC's, not that this matters.

By default, All domain members (including DC's) are in the 
'Default-First-Site-Name' site and you cannot decide which DC to use, 
any of the DC's in the site will be used.

You can create a new site and move the Samba DC to this, then move the 
required domain clients to the same site. Now, by default, the clients 
in the site will use the Samba DC, unless it goes down, at which point 
any DC will be used.

Can I suggest an internet search on 'active directory sites'

That is correct, basically you use dns to find DC's  and then the code 
decides which DC to use.
