Are you sure you want to do this? Giving non-admin users local logon rights
to a DC is not a good idea from a security point of view. If the goal is to
allow these users to manage accounts you can simply install the AD Users &
Computers console on their local PC and delegate the appropriate
permissions.
But anyway, in order to do this you have to do two things. Give the users
the right to log on locally to the DC and add them in to the security tab in
RDP properties. (Neither is recommended, I strongly suggest you find a
workaround)
