Per-user connections in Business Scorecard Manager

Hi,

Have implemented stricter security around A.S (have removed the Everyone from roles and have added specific users to have access to A.S)

When I go to BSM and try to edit / test the connection to the existing datasource, it does not return anything.

Found a website that said it might be an option the change the web.config files and set ConnectionPerUser = TRUE, where it's currently ConnectionPerUser = FALSE.

Now, sharepoint's breaking and I can't view any of the scorecards.

Has anyone tried to implement stricter security around Analysis Services

Thanks
