|System Settings, Defaults, Clusters, and Active Directory Authentication|
You can update system properties manually in the properties.txt file to enable or disable certain features.
After updating the properties.txt file, make sure you restart the server to enable or disable the new settings. For a list of properties that you can manually update, see Hidden Properties.
If your environment uses a cluster, the properties.txt file must be updated on both the servers in the cluster. When the Vocera Voice Server is upgraded, the modified properties must be manually updated again.
