Description

In cloud deployments, Ranger will be deployed on a host that does not have a Public IP (or may have one, but the ports will not be opened). The Ranger UI will be accessible via Knox proxy. 

When a service is already proxied via Knox, the easiest way to propagate the user identity is via the "trusted proxy" pattern.
