[Samba] machine authentication at Active Directory

[Otto Fuchshuber Filho]

On a 802.1X environment, it's possible to permit a windows 
desktop gain access to the network by using only machine 
authentication at the Active Directory (no need for login + 
password).
Is it possible to do the same with a Linux desktop with samba?  I 
mean a Linux desktop pass machine credentials to Active Directory 
as windows do (SID), without any login and password.
