Hi Isaac:
Thanks for brining this to our attention. While you found the answer, we would still like to include this info in our documentation. We will look into this and a bug will be filed against the document MS-PAC if needed

Looking at samba code I can see these correspond to:

                PAC_TYPE_ATTRIBUTES_INFO = 17,
                PAC_TYPE_REQUESTER_SID = 18

Please ignore my request, thanks.
