在Cakephp 2中的自定义身份验证中使用用户模型

I am using a custom authentification object in cakephp.

In AppController :
$this->Auth->authenticate = array('Ldap','Database');

I need my custom auth component to connect to the database. I have created the file DatabaseAuthenticate in Controller/Component/Auth/DatabaseAuthentification.php In my custom object I need to request a table in my database. I have tried some function than a controller

public $uses =array('Car', 'Bike'); 

But it doesn't work and I don't know how to do it.

cakephp2? you could try:

$model = ClassRegistry::init('Yourmodel');

Simple query with your model into your component

$result= $model->find('all');
