Abstract
A method is disclosed for providing user access control for a plurality of resource objects within a distributed data processing system having a plurality of resource managers. A reference monitor service is established and a plurality of access control profiles are stored therein. Thereafter, selected access control profiles are exchanged between the reference monitor service and a resource manager in response to an attempted access of a particular resource object controlled by that resource manager. The resource manager may then control access to the resource object by utilizing the exchanged access control profile. In a preferred embodiment of the present invention, each access control profile may include access control information relating to a selected user; a selected resource object; a selected group of users; a selected set of resource objects; or, a predetermined set of resource objects and a selected group of users.
