Detailed Description

Class ilRbacAdmin Core functions for role based access control.

Creation and maintenance of Relations. The main relations of Rbac are user <-> role (UR) assignment relation and the permission <-> role (PR) assignment relation. This class contains methods to 'create' and 'delete' instances of the (UR) relation e.g.: assignUser(), deassignUser() Required methods for the PR relation are grantPermission(), revokePermission()
