Deletion or movements of all leaf objects can have a major effect. By default, the check box is selected and can be deselected.Īlthough you can configure every object in Active Directory by using these ACEs, it's best suited for organizational units.

To do it, use Active Directory Users and Computers, ADSIEdit, LDP, or the DSACLS command-line tool. To prevent the accidental deletion or movement of objects (especially organizational units), two Deny access control entries (ACEs) can be added to the security descriptor of each object (DENY DELETE & DELETE TREE) and one Deny access control entries (ACEs) can be added to the security descriptor of the PARENT of each object (DENY DELETE CHILD). When you restore a deleted object, you must restore the former values of the member and memberOf attributes in the affected security principal.
