Homepage, how to redirect to users/signin page?

[Leadrive]

Hi,
controllers/home.js

  ip = 'owner-test-ip';
  Users.findOne({ip_address: ip}, function(err, result){
    if (!err && result){
      // request to moximo server for detect email and token : {email: result.email, token: result.password}
      req.body = {
        email: result.email,
        password: result.password
      };
      AuthController.sign_in(req, res, function(err, user){
        //if (err)
        //  return res.redirect('http://moximo.com');
        var ctx = {title: config.app.title, error: null};
        res.render('owner/create_room', ctx);
      })
    }
    else {
      // redirect to moximo site
      res.redirect(config.mainServer);
    }
  })

Now, the users table is empty, the program will redirect to moximo site.

If user not exist in db, it redirect to main site.
Originally, in the development mode, you should insert two test user in the user table based on user table structure
