[K12OSN] kinit: clock skew too great

This error means that the time on the kerberos client is out of synch with
kerberos server.  The kerberos server in this case is your AD controller.  I
believe, by default, the kerberos server will refuse to issue  tickets if
the clocks are out of synch by more than 5 minutes.

To avoid this problem, you should use the AD controller as the primary ntp
source for all AD members. This way your clients are always in synch with
the AD controller.  To automate this, I  setup  cron jobs  on all Linux AD
member servers to execute the following:

# /sbin/service ntpd stop; /usr/sbin/ntpdate <ip address of AD server>;
/sbin/service ntpd start

The command above stops the ntpd daemon, updates the system time  with AD
controller then restarts ntpd daemon.
