<?php
App::uses('BaseAuthenticate', 'Controller/Component/Auth');

/**
 * Uses the Facebook Connect API to log in a user through the Auth Component.
 * 
 */
class FacebookAuthenticate extends BaseAuthenticate {
	
/**
 * Settings for this object.
 *
 * - `fields` The fields to use to identify a user by.
 * - `userModel` The model name of the User, defaults to User.
 * - `scope` Additional conditions to use when looking up and authenticating users,
 *    i.e. `array('User.is_active' => 1).`
 *
 * @var array
 * @todo Implement
 */
	public $settings = array(
		'userModel' => 'Users.User',
		'fields' => array('username' => 'email', 'password' => 'password'),
		'scope' => array('User.active' => 1)
	);
	
	public function authenticate(CakeRequest $request, CakeResponse $response) {

		return $this->facebook->getUser(); // your code here..
	}
}

One question, I'm new to CakePHP 2 ..

where is the file FacebookAuthenticate..? And sample Use..?
Full Path "/app/.../.."?

Load Vendor App::import('Vendor', 'Facebook'.DS.'facebook'); ..?

thanks

Put this FacebookAuthenticate.php to app/Controller/Component/Auth/ package.

This is just a proof of concept of configured Auth "adapters"

eg. $this->Auth->authenticate = array('Facebook', 'Form')
