Major Description
In the current policy model (in 0.6), adding an user/group to allowExceptions does not automatically deny access to the user/group; the user/group should explicitly be added to denyPolicyItems. Similarly adding an user/group to denyExceptions does not allow access to the user/group; the user/group should explicitly be added to allowPolicyItems.
While this behavior offers flexibility, it does not seem very intuitive for many users. Hence this JIRA to ask for change in the policy engine to implicitly treat allowExceptions as deny and denyExceptions as allow.
