access control List

1. Extension of the conventional permission concept for files and directories. These allow a more fine-grained control of the access permissions.2. In eDirectory, an optional, multivalued property of every object. The ACL lists the objects (trustees) that can access the object, along with their explicit rights assignments. Each value contains a complete object (trustee) name, an indication of the type of rights held by the trustee, the specific rights settings, and an indication of whether the rights are inheritable. Any inherited rights filters that have been set on this object are also included.3. In Novell exteNd, the association of an access right with one or more principals. Called an ACL. You use ACLs to specify known users and groups that have a particular type of access to a particular element.4. In NetWare for SAA, a list of users or groups that have exclusive rights to a dedicated LU, OS/2 downstream PU, or LU pool. 5.
