Add the user to predefined Ranger access policies

After assigning the EnvronmentUser role to the new user, you must add the user to the appropriate predefined Ranger access policies for NiFi and NiFi Registry. These policies determine what the user can command, control, and observe in a NiFi dataflow or in the NiFi Registry.

Each predefined Ranger access policy confers specific rights to NiFi or NiFi Registry resources. When an authenticated flow-management user attempts to view or modify a NiFi or NiFi Registry resource, the system checks whether the user is associated with the specific Ranger access policy that confers the privileges to perform that action.
