Solution and reference
Check whether the group name registered on
the machine is correct and whether the DC
settings are configured correctly.
Check whether the realm name registered on
the clock at the KDC (key distribution center)
and the clock of the device are

Check the login user name and/or password
of the user registered on the server.
Try again later. If the problem persists, check
whether the machine is under an authentication
attack. The attack status can be checked by the
screen message, in the system log, or in the e-
mail notification sent to the administrator.
