Fetchxml and sharepointdocument entity

Hi All, 

I have used the following fetchxml query before:

<fetch version="1.0" output-format="xml-platform" mapping="logical" distinct="false">
  <entity name="sharepointdocument">
    <attribute name="documentid" />
    <attribute name="fullname" />
    <attribute name="relativelocation" />
    <attribute name="sharepointcreatedon" />
    <attribute name="filetype" />
    <attribute name="absoluteurl" />
    <attribute name="modified" />
    <attribute name="sharepointmodifiedby" />
    <attribute name="title" />
    <attribute name="readurl" />
    <attribute name="editurl" />
    <attribute name="author" />
    <attribute name="sharepointdocumentid" />
    <attribute name="ischeckedout" />
    <attribute name="locationid" />
    <attribute name="iconclassname" />
    <order attribute="relativelocation" descending="false" />
    <filter type='and' >
        <condition attribute='regardingobjecttypecode' operator='eq' value='1' />
        <condition attribute='regardingobjectid' operator='eq' value='81a59c0a-c11d-ed11-b83d-00224812b54e' />
    </filter>
  </entity>
</fetch>

but I am getting the following error in a new install of CRM and SharePoint. The doc integration is working, the docs show up there in files against the entity in CRM and in SharePoint so I am not sure what the issue could be all of a sudden:

"At least 1 Claim must not be NULL, current claims are : nameid=;nii=urn:federation:microsoftonline "
