When I get to install NS7

Hi all
This is my very simple setup of my network, I have a DC Servere that has all my usere, runing Active Directory, DHCP and DNS. Every user has a user name and password of course, giving them certain access to certain folders.
Is it possible to give certain users access to internet using the same username and password they logon. I want to give users access to the internet by their username and password instead of by IP (which I am doing now)?
this way I make all users DHCP… ones with the right to internet can logon on any computer and have that access

AFAIK, automatic authenticated access should work by default in an Active Directory setup using NethServer 7.
I don’t have such a setup in production, but I’m told that you shouldn’t need any special configuration.
