I am trying to set up a VPN 3080 concentrator to support PPTP clients. Authentication is done through a RADIUS server that supports MS-CHAPv2. Using the built in PPTP client in Windows XP, I have set up the security parameters to use MS-CHAPv2.
Looking at the concentrator logs, authentication is successful:
Authenticated successfully with MSCHAP-V2
However, the client closes the connection. A window appears in the XP client showing the error:
Error 778: It was not possible to verify the identity of the server.
With the same concentrator, I can connect successfully using PAP and pointing to a different authentication server that only supports PAP.
Need to know how to enable the client to accept the identity of the concentrator.
