[Samba] Google Apps Directory Sync Password Attribute

[Shem Pasamba]

Hello,

I'm trying to synchronize users with samba4 and Google apps using Google 
Apps Directory Sync. It's asking me to enter the user Password 
attribute. May I know what attribute does samba4 use to store user 
passwords? Also, what hash does it use? SHA1? or MD5? I imported the 
users using pdbedit.

Thank you in advance.

Sincerely,

Windell Shem Pasamba
