The situation is that we have a web Server that is NOT the SSAS server.
We want to provide HTTP access to the Cube.
We do NOT want the users to have credentials in AD.
The Cube does NOT need to differentiate users.
Ideally, there would be a single AD user (or local somewhere) that is granted access to the cube, this user is setup in the IIS App Pool. We then have anonymous authentication only enabled so that all users can access it.
I've tried changing the identity of the App Pool to an AD account, and verified that this user does have access the cube. However, all I get in Excel when I try to connect is the "User ID/Password incorrect" message.
We do not want to put the msmdpump interface on the same server as the SSAS instance if at all possible.
Is this a non-standard use-case? I can't seem to find any documentation for it as the "Anonymous" authentication information the MSDN article says that you need to add the "IUSR_<computer name>" account to SSAS, but this is a local account and therefore can't be accessed by the SSAS instance.
Any help would be greatly appreciated.
Thanks
Martin
