[Samba] winbind without localuser account

[Paul Matthews]

this is the how-to i followed to get to where i am.

http://www.yourhowto.org/content/view/31/9/

this is how simple my pam module is at the moment

auth            required      pam_winbind.so
account         sufficient      pam_winbind.so

using that pam module, i can only sign in if i have a local account and an
Active directory account.

or it will work with only a lock account.
