Today at work I made a Zend_Acl – Resource / Role / Privilege Viewer that I wish I could share, but can’t. Pretty straight forward, globs the resources by their file names and instantiates all the roles on another glob. Overrode the allow/deny in Zend_Acl to save the privileges and then use that to display a table of all the isAllowed calls for a specific resource for all the roles for their privileges.
Was looking around to see if there are any open-sourced projects and didn’t find any.
