Dynamic groups and nested group support

Dynamic groups contain a group name and membership criteria:

• The group membership information is as current as the information on the user object.

• There is no need to manually maintain members on the group object.

• Dynamic groups are designed such so an application does not need to pull a large amount of information from the directory to find out if someone is a member of a group.

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.

Dynamic and nested groups simplify WAS security management and increase its effectiveness and flexibility. You only need to assign a larger parent group if all nested groups share the same privilege. Assigning a role to a single parent group simplifies the runtime authorization table.
