Before You Begin
The GNOME screensaver is displaying on a desktop that you logged in to with a smart card PIN.
Then press the Enter or Return key.
The smart card reader's green LED blinks as the card is being read and the subject_mapping field of the certificate is verified.
A "verifying certificate" dialog box displays.
If the dialog box displays Error 2320: Wrong smartcard PIN, press the Dismiss button and type the PIN again.
