It should !
See also my script :

Yes it does. Look at "Builtin\system" which is also "NT Authority\System.

Correct, thats by design, and if you get access denied, you did hit the "winbind" "user SYSTEM" bug(s).
Fix, use acl_xattr:ignore system acl = yes for now.

Yes, which is totaly correct.

No, the computer uses system, but if you test manualy it sets the computername.
