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.
