I've been trying to get our Cisco ISR 2811 to authenticate the VPN clients towards an Active Directory server (so that the Cisco VPN client asks the user for username/password).
Googling around has only given me instructions on how to do it with a PIX/ASA, I would like to do the same on the router.
Thanks,
Mattias
