          This module will test Kerberos logins on a range of machines and
          report successful logins.  If you have loaded a database plugin
          and connected to a database this module will record successful
          logins and hosts so you can track your access.

          Kerberos accounts which do not require pre-authentication will
          have the TGT logged for offline cracking, this technique is known as AS-REP Roasting.

          It is also able to identify whether user accounts are enabled or
          disabled/locked out.
