Bingo! If i set:

Things start to work; i mean 'start' because effectively a disconnection of
the laptop basic nss survive (eg, i can do 'id gaio' and i get some output),
but still if i lock the screen, i cannot login back anymore (due to
timeouts, i suppose; it is a bit hard to debug a disconnected laptop... ;-).
I've also reboot, and in logon screen GDM say me that i'm logging in with a
cached credential (wow!), but after 15 minutes i was still logging in,
screen saver start and so i was back to login screen.
This lead to me to the considerations:
1) winbind offline logon work only in 'rid' mode, or at least does NOT work
in rfc2307 mode.
2) i think this is a bug...
Andrew, what do you think?
