Sorta. D-Bus is only used to communicate with the authenticator by saying 
"Hey! We need to make sure this person knows the password!".

PolicyKit uses an external helper (polkit-auth) set suid-root to directly read 
and write to the authentication database. The library wraps around calling the 
program. The library also uses the dbus calls to the authenticator when the 
helper says authentication is required.
