)

Parameters

userName

// MUST NOT be used in a production environment because it is NOT secure.

    if (null == userName || null == password)
    {
        throw new ArgumentNullException();
    }

    if (!(userName == "test1" && password == "1tset") && !(userName == "test2" && password == "2tset"))
    {
        throw new SecurityTokenException("Unknown Username or Password");
    }
