  • Patent number: 6212511
    Abstract: An access control database defines access rights through the use of access control objects. The access control objects include group objects, each defining a group and a set of users who are members of the group, and rule objects. A first subset of the rule objects each specify a set of the group objects, a set of the management objects, and access rights by the users who are members of the groups defined by the specified set of the group objects to the specified set of management objects. The access control server responds to the access requests from the users by granting, denying and partially granting and denying the access requested in each access request in accordance with the access rights specified in the access control database. A database management system receives management information from the network and stores that information in a set of database tables.

  • Patent number: 6064656
    Abstract: An access control database defines access rights through the use of access control objects. The access control objects include group objects, each defining a group and a set of users who are members of the group, and rule objects. Some of the rule objects each specify a set of the group objects, a set of the management objects, and access rights by the users who are members of the groups defined by the specified set of the group objects to the specified set of management objects. A plurality of access control servers are used to process access requests. Each access control server controls access to a distinct subset of the management objects in accordance with the access rights specified in the access control database. At least one of the access control servers receives access requests from the users and distributes the received access requests among the access control servers for processing. A subset of the access requests specify operations to be performed on specified sets of the management objects.
