/*
Getting these errors when trying to log in. I'm using zend_auth with a doctrine adapter.

Strict Standards: Declaration of HR_Controller_Plugin_Auth::preDispatch() should be compatible with that of Zend_Controller_Plugin_Abstract::preDispatch() in /media/data/dev/php/mjfreg/library/HR/Controller/Plugin/Auth.php on line 61

Fatal error: Cannot redeclare class Registration_Model_Acl in /media/data/dev/php/mjfreg/application/models/Acl.php on line 38


When I remove the Auth test and set the role to admin or guest the acl works fine.
