Is there a simple way to prevent unauthenticated users from accessing the internet from the inside?
It is my understanding that you cannot negate AD Groups? True?
I was hoping to create a policy like this that would deny any unauthenticated users from accessing the internet.
Zone Address User Zone Address Action
LAN Any domain/domain users WAN Any Allow

The simplest being deny all access to 'unknown-user' in the "source user" field. That way only authenticated users will be able to gain access to whatever rules you permit whereas any unauthenticated traffic will be dropped.
Does that help?
If you setup a security policy like:
User: domain/domain users
followed with a (the built in default deny rule doesnt log):
Options: Log on session end
Then only clients from your LAN zone which are authenticated against the AD and belongs to the domain users group will be allowed to pass through.
