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.
