Hier noch eine kleine Lesehilfe:
PSDK on IADsGroup.ADsPath The ADsPath string of this object. The string uniquely identifies this object in a network environment. The object can always be retrieved using this path.
The globally unique identifier of the directory object. The IADs interface converts the
GUID from an octet string, as stored on a directory server, into a string format.
