The Zend Developer Zone has posted a new tutorial (from Aldemar Bernal) about some of the basic use of the Zend_Acl component of the Zend Framework.

So, what is wrong with Zend_Acl and the current MVC implementation in the Zend Framework? there is nothing wrong, it is just that it gets not too obvious for developers how to achieve an optimal integration between these two important parts of the framework.

He talks about the proposal that's out for a potential update to the component, the two key points being the front controller plugin and a new action helper. He includes some sample code showing how to set it all up including a "denied" controller to handle the failures.
