If the schema doesn't include the attribute you need, you can also extend the schema by creating the new attribute. All object classes inherit a default ACL template from the Top object class. This ACL template provides a minimum amount of security. It gives all objects the rights to supervise any objects they create. This ensures that every object added to the NDS tree has a supervisor.
Objects also inherit default ACL values from their super classes.
Therefore, every object class inherits a default ACL template from the Top object class. When an object is created, its ACL contains the values that are in the default ACL template for that object. The creator of the object has effective rights comparable to those in the default template. In this case, the rights are not granted explicitly. In addition to the default ACL template they inherit from Top, object classes inherit any default ACL templates that are defined for any of their super classes.
