PPTP VPN connection on 3060 using MSCHAPv2

Brian M · ‎10-22-2007

Hello, I cannot seem to get MSCHAPv2 working between a 3060 concentrator and Windows XP SP2. ACS always reports that the MSCHAP password is invalid.

If I only use MSCHAPv1 authentication work fine, and even if I test authentication from the concentrator I get a success message. For some reason, no clients using PPTP can authenticate with v2.

I did verify that MSCHAPv2 was checked on in the ACS configuration and my PPTP tab on the VPN group is selected to use v2 as well.

Any Ideas?

Thanks!!

VPN server allows MSCHAP v2 with its internal user authentication server but not with external server. If you check Required under PPTP Encryption, you must allow one or both MSCHAP protocols and no other.
