Hi

 

I am playing with the current beta of the ODATA services and am running into an issue with the retrieval of tag values....

 

I am using Excel 2013 and power query in the same way as is described in the vCamplus Live labs...

 

Strange thing is that attribute values that are coming from an (internal ) table query ARE returned....

 

so my first 'hunch' was that is was a security issue with the webservice not passing the user identity so I changed the authentication mode of the ODATA webservice itself and have it run with a fixed ( local admin) account...

 

but that also did not work....any ideas ?
