Dynamic and nested groups simplify WebSphere Application Server security management and increase its effectiveness and flexibility. Dynamic groups contain a group name and membership criteria:
Nested groups enable the creation of hierarchical relationships that are used to define inherited group membership. A nested group is defined as a child group entry whose distinguished name (DN) is referenced by a parent group entry attribute.
You only need to assign a larger group if all nested groups share the same privilage. Assigning a role to a single parent group simplifies the run-time authorization table.
