Report to Identify Devices with Deleted or Non-Existing Assigned Credentials

NetBrain currently stores Telnet/SSH credential values directly with each device record rather than maintaining a live reference to the credential definition. As a result, when a credential is deleted from Network Settings, devices that were assigned that credential retain the stale username and password values, and administrators have no way to identify which devices are affected. This enhancement would introduce a report or search capability that identifies all devices currently assigned a credential that no longer exists in Network Settings. Customers would benefit from the ability to proactively locate and remediate devices with orphaned credential assignments, improving credential hygiene and reducing the risk of failed or unauthorized access attempts.
