The OES User Rights Map (NURM) utility is used by administrators to map the Access Control List (ACL) of NSS resource that is owned by an identity in eDirectory to an identity in Active Directory. It maps the users and groups from eDirectory to Active Directory using a common name or any other field that is selectable by the tool. For more information, see NURM (OES User Rights Management) in the OES 2015 SP1: NSS AD Administration Guide.
