I believe to do that you need a RADIUS or TACACS+ box for authentication, like Cisco ACS. The PIX firewall can be configured for local or remote authentication. Local you would have to configure your all of users locally on the PIX.

With Cisco ACS you just point the ACS to your WIN2000 AD as an external database. All you need to do is configure the ACS to use your PIX as a NAS (network access server) and add the following to your PIX: ACS is the name of my AAA server


aaa-server ACS protocol tacacs+

aaa-server ACS (inside) host 1q2w3e4r5t timeout 10


crypto map vpnmap client authentication ACS

This will cause all users initiating a remote VPN connection to be prompted for a user name and password which the ACS will forward to your WIN2000 AD database.
