A gateway between client manager applications and an enterprise manager may be provided to manage various networked objects. In one embodiment, CORBA-based TMN manager applications may be communicatively coupled to a CORBA Object Request Broker (ORB) and may be operable to send Interface Definition Language (IDL) requests to, and receive IDL responses and CORBA events from, managed objects through the CORBA ORB. The client manager may first be authenticated to the gateway by username and password, or other validation information associated with the client manager, which may be represented in a user profile. Once the initial client authentication is accomplished, the gateway may provide object-level access control between manager applications and managed objects at an individual object level so that one of the managers is granted access to one of the managed objects while being prevented from interfacing with a different one of the managed objects.
