[Samba] Password Storage on Samba Primary Domain Controller

[Joseph Bell]

I've built a Samba PDC using the instructions at
https://wiki.samba.org/index.php/Setting_up_Samba_as_an_Active_Directory_Domain_Controller
and
have had great success using it in an enterprise setting.

As a part of a compliance audit I need to articulate clearly the password
encryption mechanism of my domain controller.  Is there reference
documentation on how user passwords are stored in a PDC configuration?
(Note: I used the term 'stored' but am assuming some type of salting,
hashing, etc. mechanism is actually used.)

Thanks,
Joe
