> Authorizations given to role-based principals must be dereferenced upon user login.  These authorizations are dynamically determined based on the user's set of roles.  
> In {{org.apache.ambari.server.security.authorization.AmbariLocalUserDetailsService#loadUserByUsername}}, the set of {{GrantedAuthorities}} the authenticated user is calculated.  During this process, using the set of {{cluster-level roles}} a user is granted, any permissions given to matching role-based principals should be given to the user. 
> This essentially work like giving privileges to a group of users calculated at runtime. 
> A use-case to support the need for this is to assign access to a view to all users with some specific role. Currently we can assign access to a view to a specific user or group by assigning that user or group the {{VIEW.USER}} role applied to the specific view.  To assign access a view to users who have a specific role, a {{role}} will need to behave like a {{principal}}.
