Gergely Hodicska has
posted about some hacking he's down with the Zend_Acl package in the Zend Framework to make support for custom roles and resources.
I found that the base Zend_Acl package has some limitation/problem if you want to use it in a bigger real life project. Zend_Acl supports only logical roles, resources so I decided to extend it to allow using custom roles and resources which can represent existing entities (for example users/groups and topics in a database)
He
talks some about the package and its current functionality, including the limitations he ran up against. He came up with a structure for what he wanted (
seen here) and set out to extend the class, making an interface and implementing it with his own loading method.
His source code can
be downloaded here.
