Entities are auditing like groups, but the categories are: entity, and the actions are addEntity, updateEntity, and deleteEntity.
There are three change log types for entities: ENTITY_ADD, ENTITY_UPDATE, ENTITY_DELETE. All other actions will appear under groups. e.g. if you add a privilege to an entity it will appear like a privilege is added to a group.
The point in time information is available, similar to point in time information on groups.
