How to use multiple Auth components?

I configure a Auth component to "Admin page", using the users model. But now, I also want create/configure a Auth to the clients. I try "rewrite" the inialize()

//This is in my ClientsController.php
public function initialize()
{
    $this->loadComponent('RequestHandler');
    $this->loadComponent('Flash');
    $this->loadComponent('Auth', [
        'authenticate' => [
            'Form' => [
                'userModel' => 'clients',
                'fields' => ['username' => 'client_email', 'password' => 'client_password']
            ]
        ],
        'loginRedirect' => [
            'controller' => 'Clients',
            'action' => 'index'
        ],
        'logoutRedirect' => [
            'controller' => 'Clients',
            'action' => 'login'
        ],
    ]);
}

With this, I receive this log(if uses parent::initalize() receive the same)

[RuntimeException] The "Auth" alias has already been loaded with the following config: array (...

I not want create a "Auth" manualy. How to use more of one Auth?

Thanks....

Reconfigure

You don't necessarily need to use multiple auth component instances, you can simply reconfigure it in the extended controller, using the components config() method, something along the lines of:

public function initialize()
{
    parent::initialize();

    // ...

    $this->Auth->config(
        [
            'authenticate' => [
                'Form' => [
                    'userModel' => 'clients',
                    'fields' => [
                        'username' => 'client_email',
                        'password' => 'client_password'
                    ]
                ]
            ],
            'loginRedirect' => [
                'controller' => 'Clients',
                'action' => 'index'
            ],
            'logoutRedirect' => [
                'controller' => 'Clients',
                'action' => 'login'
            ],
            'storage' => [
                'className' => 'Session',
                'key' => 'Auth.Client'
            ]
        ],
        null,
        false
    );
}

Note the use of the storage option, you should define a different key here (the default is Auth.User), otherwise an authenticated client might be able to access the admin area and vice versa, as the user data would get stored in the same session key!

Use aliasing

You could use multiple auth components if required, to do so you'd have to use aliasing, so that the components don't try to override each other:

$this->loadComponent('ClientAuth', [
    'className' => 'Auth',
    // ....
]);

Don't forget to use a different session key in this case too!

You'd access that component instance as $this->ClientAuth accordingly, and you may have to allow access to the login() method via $this->Auth, ie. in ClientsController::initialize() or beforeFilter() do:

$this->Auth->allow('login');

There might be further side-effects, so be careful.
