[Samba] Internal DNS entries not created on Domain join of Windows computer, but with Linux it works!?

[Jakob Curdes]

Hello all, hello Patrick,

I never had problems with that mechanism in other installations. Might 
it be worth wile to try a provisioning with external DNS / BIND instead?
This is a larger production setup so I am reluctant to start with an 
error condition that is not unserstood well. We are using samba 4.15, 
might the previous version change something?

Thanks and best regards, Jakob
