In a new project we will be creating an SSRS in Sharepoint integrated mode. For this we'll need SQL Server and Sharepoint on that box.
We'll also have one or more SharePoint Web Front End (WFE) servers. To allow them to connect to the SSRS-in-sharepoint-mode box, and to present the user with the right user interface for doing so, I believe we can install the Reporting Services Add-In for Sharepoint on the WFE servers.
The question is, do we need to have SQL Server license for each WFE server where we use the Reporting Services Add-In, or is it free to use?
We've had advice that we need to buy a SQL Server license everywhere we use the add-in, but I am not sure this is correct.
Thanks in advance,
Rich
