What I am trying to do is authenticate internal users going out to the internet thru a PIX running latest IOS 8.02. Basically the PIX should intercept the new outbound session and redirect the user to a web server where they are prompted for userid and password. This web server then sends the info back to the PIX which authenticates it to a RADIUS server. If the login is good then the user session resumes outbound to the original web request.
Is this possible?? Thanks
