The NTDSSettingsObjectDN contains the distinguished name of the NTDSSettingsObject directory object that represents this domain controller.

 <xs:element name="NTDSSettingsObjectDN" nillable="true" type="xs:string" />

The NTDSSettingsObjectDN element is populated from the nTDSDSA!distinguishedName attribute on the nTDSDSA object specified by the GetADDomainControllerRequest/NtdsSettingsDN (section input parameter element. If the nTDSDSA!distinguishedName attribute is not present or cannot be read due to the client lacking access rights to read the attribute, the server retruns a null ActiveDirectoryDirectoryServer/NTDSSettingsObjectDn element.
