CakePHP's magic findBy methods return in the same format as find('first') so your $config result will be indexed by the model's alias, not the field you've searched with. Therefore, $config['Username'] should be $config['User']. So your controller action should look like:-

public function _initPaypal() {
    $user = $this->User->findByUsername('admin');
    $config = $user['User'];
    App::import('Vendor', 'Paypal/paypal');
    $this->paypal = new Paypal($config['paypal_api_username'], $config['paypal_api_password'], $config['paypal_signature']);
}

I've modified your variable names a little to make the difference between the query result ($user) and $config (at first read this confused me).

I don't see why your example code would have worked anywhere without the correct alias index.

If this doesn't fix your problem check what $this->User->findByUsername('admin') is returning using either debug() or print_r() and make sure it is generating the expected SQL query (and that that works on your server).
