// AuthenticateUser - Called on recept of a 401 or 407 status code
// from the Web Server. This function should attempt to
// validate the Server's 401/407 response, and generate
// ERROR_SUCCESS if it accepts this Server for authentication
// Otherwise this function should returns an appropriate
// error found in wininet.h, or winerror.h
//
// lppvContext - pointer to Context pointer that will be passed on
// every unquie conversation with the Server. Will be a pointer to a
// NULL the first time this function is called for a unquie session.
// Its the Function's responsiblity to allocate or generate a unquie context
// value that will be passed on future calls.
//
// lpszServerName - Host Name of Web server.
// lpszScheme - Name of Authentication Scheme being used, ie Basic, MSN, NTLM..
// dwFlags - Flags.
// lpszUserName - Possible UserName if availble.
// lpszPassword - Possible Password if availble.
//
// RETURNS:
// ERROR_SUCCESS - Means it accepts this connection as valid, and
// asks for the authentication to continue by restarting
// the HTTP connection, and calling PreAuthenticateUser BEFORE
// that new HTTP connection is opened.
//
// ERROR_INTERNET_INCORRECT_PASSWORD - Means we do not understand this
// username and/or password that is passed to us. Will
// return to User or Application for new username and password.
//
// ERROR_INTERNET_FORCE_RETRY - An additional 401/407 response may
// need to be generated from the server. Forces PreAuthenticateUser
// to be recalled, and new HTTP connection/request. The difference
// is WININET will expect a 401/407 to be generated from this request.
