Following principle of Least-Privilege Administrative Model I'm making custom group for managing domain, that would be less privileged than Domain Administrator. For starters it should have permission for adding computer to a domain.
I'm testing many different ways of achieving this and I came across this article from Microsoft: https://docs.microsoft.com/en-us/troubleshoot/windows-server/identity/access-denied-when-joining-computers
It states:
Locate and right-click the OU that you want to modify, and then select Delegate Control.
But I'm not sure what OU I should actually pick and I couldn't find any explanation inside the article (or am I blind?).
So which OU should it be? Built-in Computers? OU where I want the computer to ultimately reside (like custom OU "Servers" or "Workstations")? Something else?
Currently I delegated control over the whole domain (I have single domain in my environment) and it is working, but I'm not sure it is either secure or good practice?
