Use the Security page to view or change the list of objects that the driver is explicitly security equivalent to. This object effectively has all rights of the listed objects.
If you add or delete an object in the list, the system automatically adds or deletes this object in that object’s “Security Equal to Me” property. You don’t need to add the [Public] trustee or the parent containers of this object to the list, because this object is already implicitly security equivalent to them.
Designer does not list the users the driver is security equals to.
