EnableCHAP Property of the IFPCVpnPPPSettings Interface

CHAP is a challenge/response authentication protocol for Point-to-Point Protocol (PPP) connections that applies the Message Digest 5 (MD-5) hashing algorithm to a combination of the challenge string issued by the authenticating server and the user's password, and then sends the result in the response.
