  <p>EDIT:
  Please note additionally that this call is through another data pump which can successfully connect to the SSAS instance. </p>
  
  <p>EDIT2: 
  The error message looks to be coming from SSAS - so the request IS getting there. But it is failing on the user. Would I not appear coming through as the same user as the other data pump? Both data pumps are using Anonymous Authentication.</p>
  
  <p>Actually any data on how the msmdpump.dll works would be great. All I've found is how to set it up not actually how it works.</p>
  
  <p>Thanks in advance.</p>
