[Samba] PDC broke after upgrade

[Mat Enders]

I upgraded from Debian Lenny (Samba 3.2.5) to Squeeze (Samba 3.5.6) and now
my PDC does not work.

In the past when upgrading from one release to another all of the machine
trust accounts no longer worked but I was able to just rejoin then to the
domain.  Now however the join fails with unknown user and bad password.  I
have always used root and roots password what am I missing?  What changed
between these 2 releases?
