This step-by-step article describes how to modify Active Directory object attributes. The example in this article changes the defaultSecurityDescriptor attribute of the Organizational Unit object to remove the Read permission from the members of the Authenticated Users group.

This operation is an advanced operation that is best performed programmatically by experienced programmers and system administrators.
