Question : Microsoft PPTP-VPN client to PIX 501, How Do I connect to Win2003 Domain?

Hello, I have a MicroSoft VPN Client using PPTP to connect to a PIX 501. The client OS is a XP. After making my connection to the PIX FireWall I am unable to connect to the Windows 2003 Domain Server. I would like to have a one password authenication if possible. How do I set this up or allow users to connect a session to the Domain Controller once a VPN session is established?

The PIX cannot "authenticate to the Domain Controller". The KB article refers to a Cisco "router" and that does not mean "pix".

The PIX can ONLY forward the Client's request to authenticate, via the RADIUS protocol, to the IAS server which itself communicates with the domain controller.
There is no direct kerberos communications between the PIX and the Domain controller.
