[Samba] restrict shares to joined computers

[me at electronico.nc]

Samba 4.1.4 AD/DC (git) on Ubuntu 12.04.4 LTS X64

Hi all,

It seems that client's authentication on shared folders is only done via 
login/password in AD.
This means that a user coming in office with his personal laptop can 
connect to the shared folders he has rights to, using his AD 
credentials, even if his laptop is not joined to the domain.

Is there a way to restrict shares to only joined computers ?

Unfortunately, I have no experience with real Windows server, so I don't 
know if it's the case with them.

Thanks in advance for your time.

Nicolas
