Item level Roles were created for windows users account on the Report
Manager in the Properties tab of Report Manager Home page. Some with more
permissions and some with fewer permissions.
Logining in as one of the users(not the Compuer owner) and try to access the
Report Manager results in the following error.
Error Details:
Error message 401.3: You do not have permission to view this directory or
