Role Based Access Control

Question

Are there any open source, PHP based, role based access control system that can be used for CodeIgniter?

Answer 1

RBAC != ACL - Roland has the only correct answer for this question.

BTW of course it is an essential part of a framework to implement any kind of permission system - at least there is no point in using a framework, if it does not give you a well engeneered RBAC system - it might be better using a simple template system with any ORM layer then.

It is a common antipattern in the php world, that frameworks like Ruby or Django are "cloned" only as a subset of what these modern frameworks deliver - as a typical syndrome yuo see a lack of good ACL or RBAC integration into these frameworks - what essentially is a joke. There is currently only the Yii PHP Framework that comes with a decent RBAC implementation.
