CakePHP 2.x plugin for Opauth.

Opauth is a multi-provider authentication framework.

CakePHP v2.x
Opauth >= v0.2 (submoduled with this package)

Check out CakePHP bakery for tutorial and the sample branch for a quick sample app.

1. Install this plugin for your CakePHP app.
   Assuming APP is the directory where your CakePHP app resides, it's usually app/ from the base of CakePHP.

   cd APP/Plugin
   git clone git://github.com/uzyn/cakephp-opauth.git Opauth

2. Download Opauth library as a submodule.

   git submodule init
   git submodule update

3. Add this line to the bottom of your app's Config/bootstrap.php:

   <?php
   CakePlugin::load('Opauth', array('routes' => true, 'bootstrap' => true));

   Overwrite any Opauth configurations you want after the above line.

4. Load strategies onto Strategy/ directory.

   Append configuration for strategies at your app's Config/bootstrap.php as follows:

   <?php
   CakePlugin::load('Opauth', array('routes' => true, 'bootstrap' => true));
   
   // Using Facebook strategy as an example
   Configure::write('Opauth.Strategy.Facebook', array(
       'app_id' => 'YOUR FACEBOOK APP ID',
       'app_secret' => 'YOUR FACEBOOK APP SECRET'
   ));

5. Go to http://path_to_your_cake_app/auth/facebook to authenticate with Facebook, and similarly for other strategies that you have loaded.

6. After validation, user will be redirected to Router::url('/opauth-complete') with validated auth response data retrievable available at $this->data.

   To route a controller to handle the response, at your app's Config/routes.php, add a connector, for example:

   <?php
   Router::connect(
       '/opauth-complete/*', 
       array('controller' => 'users', 'action' => 'opauth_complete')
   );

   You can then work with the authentication data at, say APP/Controller/UsersController.php as follows:

   <?php // APP/Controller/UsersController.php:
   class UsersController extends AppController {
       public function opauth_complete() {
           debug($this->data);
       }
   }

   Note that this CakePHP Opauth plugin already does auth response validation for you with its results available as a boolean value at $this->data['validated'].

7. (optional) The submoduled Opauth core library may not be of the latest build, to update to the latest:

   git submodule foreach git pull origin master

If your CakePHP app does not reside at DocumentRoot (eg. http://localhost), but at a directory below DocumentRoot (eg. http://localhost/your-cake-app),
add this line to your app's APP/Config/bootstrap.php, replacing your-cake-app with your actual path :

<?php // APP/Config/bootstrap.php
Configure::write('Opauth.path', '/your-cake-app/auth/');
