You still don't understand. It's not a feature. It is a requirement. If you don't like it, then you can't provide any of the functional parts that authpf provides. It's a requirement for rule addition and rule deletion to KNOW where a session is from. Otherwise, you might as well just use pf itself, without any logging in, because your authpf logins really mean nothing.
