There are SSRS reports that are placed in a SharePoint site with Integrated Mode. On the SharePoint site, there is a group of users that have the Read permission to the whole site.
The Shared Data Source was created through SharePoint and placed in another library in the same site as the reports. If the connection string was copied and pasted individually inside of each report (instead of using Shared Data Source), the users can view it. If the Shared Data Source is utilized instead, it seems that those with only Read permission in the group cannot view the reports.
The group should not be able to do anything else but read the reports (they shouldn't be able to modify the Shared Data Source, etc.). What needs to be done?
Note that Shared Data Source is ideal because it will eliminate the need to modify all of the reports individually in the future if the Data Source server changes.
Thank you!
