Components not loaded?

I’m trying to use the yii-user-management extension and in order to install it I need to overwrite the default

Authentification Method in the Application Configuration:



  'class' => 'application.modules.user.components.YumWebUser',


  'loginUrl' => array('//user/user/login'),


For some reason this has absolutely no effect. It is as if Yii would completely ignore that I’m loading this component and changing the loginURL and it is still using the standard UserIdentity.php.

Any suggestions are apprecitated
