[Samba] Windows 7 machine trust accounts expiring

There was an earlier thread about failing trust relationships between 
Windows 7 and Samba. Since we occasionally experience the same problem 
with Win 7 clients against a Samba 3.5.4 server, I investigated this a 
bit further.

I think it happens when
- the time to change the machine password has arrived
- the Win 7 machine is up, but no one is logged on (login box is shown 
on the screen).

To reproduce this, I reduced the machine password change interval to one 
day on a test computer, then let the login prompt sit there for a day or 
so - and indeed I could not log in anymore because of a trust 
relationship failure. I will try this a couple more times.

I hope this helps to find a remedy.
