The "Connect As" feature only changes the Asset Framework Connection and still uses the user who runs the application to connect to the Analysis service. This causes a confusion for end users as they cannot perform their analyses operations (e.g. backfilling) unless they have the Management add-in.
Would like to have this behaviour changed so that the connection to the AF Server and respective AF Services (e.g. analysis, notifications) are made with the "Connect As" user.
Organizations may disable the “run as different user” function.
