Dismiss the Network Credentials Required Message
After leaving the screen saver on a Gnome desktop that is running the Gnome Display Manager, or GDM, you might see a pop-up notification saying that network authentication is required or that network credentials are required. You can ignore the notification. The GDM process that tracks the expiration time of a Kerberos TGT might not recognize the updated expiration time of a Kerberos TGT after it is refreshed by AD Bridge.
