Once the addon is installed you have a controlpanel that provide a direct access to @@localrolesdatatables_catalog_view view where you can see every localroles of every content types. Because it use jquery datatbles you can search and filter per content / users / content type.
This view use the portal_catalog, and build a query using the context path. So if you want to have a report with only a folder (for an extranet) you just have to call the view on this folder:
mysite/extranet/@@localrolesdatatables_catalog_view
