Testing out Hybrid Auth for login to Google Apps Domain

• HybridAuth - Google Authentication
• Make sure to have Contacts and Google+ API access enabled in https://console.developers.google.com/project.
• And also make sure to have Authorized redirect URIs right.

I decided to put my domain and google secret in auth.php. Below is the structure of auth.php

// google "Client ID" and "Client Secret"
$keys = [
  'id' => "PUT_YOURS_HERE",
  'secret' => "PUT_YOURS_HERE"
];

// if you want to force user to one specific domain.
$domain = "PUT_YOURS_HERE";
