OK, i supposed also that (please, restore that on wiki), but as just stated
i've not a problem with reboot... ;-)

I'm still using my 'old' DNS and DHCP setup, and DHCP server does not assign
the AD domain to client (for windows cliend it is not needed: thay have the
AD domain dns suffix as predefined by default, after joined).

Also, as just stated, previous Ubuntu 16.04 worked perfectly with the same
dns setup, so probably it is not the culprit.

Also trying to fiddle with /etc/hosts and /etc/hostname, i was not able to
print the domain, eg:

> hostname -d
> samdom.example.com
> hostname -f
> testdm12.samdom.example.com

i get empty result (hostname -f return the host).

I've tried to disable DHCP and setup manual network connectivity (cabled)
using domain DNS (DCs)

Nothing changed.

If network is connected, all works as expected; if i disconnect cable, all
(logon, a simple 'id gaio', ...) stop instantly to work...

I'm starting to get a bit desperate...
