Understanding the "Default Rules" Tab

The Default Rules tab allows granting permissions, over application elements, to users or user roles.

The control widget displayed in this tab is what we call a ruleset editor. On the left are listed all the users and roles, the so-called "user patterns", while the right part shows all element types and access rights for which the permissions can be edited.

When loaded the grid shows the default rules for the selected user pattern.

You can see that some combinations are shown as N/A. This happens when the access right does not have a meaning for a given object type. For instance, one cannot define a permission rule for the combination Tasks/Delete on TASK type since Tasks are defined by the backend code of the application, and cannot be deleted.
