How to avoid Spotlight user to modify any Spotlight's configurations ?
This feature is available in Spotlight on SQL server Enterprise since version 8.1
From version 8.1, spotlight created new Quest Diagnostic Read-Only User group
The new Quest Diagnostic Read-Only User Group enables organizations to limit access to Spotlight on SQL Server (to read-only access) to specific users. These users can view the home page and drilldowns for connections but cannot make changes to impact Spotlight's operation.
