title: Passport.js authenticate not working
body: <p>I'm trying to set up passport for the first time and going with just a single google sign-in option.  I registered with google apis so i have all that setup.  the relavant code is below, but when my app makes the <code>'/auth/google/'</code> call it just fails with no response or error message.  I've switched up the configuration a bunch of ways to no avail.  I've also replaced the <code>passport.authenticate('google')</code> with an anonymous function with a console.log to double check my web service is operating correctly and it is.  So I know it is getting to the <code>passport.authenticate('google')</code>.</p>
  
  <pre><code>    // serialize session
      passport.serializeUser(function (user, done) {
          done(null, user.id);
      });
  
      passport.deserializeUser(function (obj, done) {
          done(null, obj);
      }); 
  
        // use google strategy
    passport.use(new googleStrategy({
        clientID: config.google.clientID,
        clientSecret: config.google.clientSecret,
        callbackURL: config.google.callbackURL,
        scope: 'https://www.google.com/m8/feeds https://www.googleapis.com/auth/userinfo.email https://www.googleapis.com/auth/userinfo.profile'
    },
    function(accessToken, refreshToken, profile, done) {
      console.log(profile);
    }
  ));
  
  
    app.use(passport.initialize());
    app.use(passport.session());
  
  
    app.get('/auth/google', passport.authenticate('google'));
    app.get('/auth/google/callback', passport.authenticate('google', { failureRedirect: '/', scope: 'https://www.google.com/m8/feeds' }), signin);
  </code></pre>
  
  <p>EDIT:
  Here is my http request, I'm using angular and this function is tied to a ng-click on a button.</p>
  
  <pre><code>$scope.signIn = function () {
      $http({method: 'GET', url: '/auth/google'}).
          success(function (data, status, headers, config) {
              console.log('success');
          }).
          error(function (data, status, headers, config) {
              console.log(data);
              console.log(status);
              console.log(headers);
              console.log(config);
          });
  };
  </code></pre>
  
  <p>Those logs return nothing</p>
