[Samba] Samba4. Unable to join to client machines.

Hi!

First poster ahoy, be gentle with me.  I've been fiddling around with 
Samba4, using the (pretty nifty) howto at wiki.samba.org.  I've followed 
it through and provisioned the active directory, I've run all the tests 
and everything seems good.  Kerberos responds as it should, dynamic DNS 
seems to be doing its thing (nothing untoward shows up with 
samba_dnsupdate --verbose) and the system times are within a couple of 
seconds of eachother, so as far as I can tell, I'm not doing anything wrong.

I have a pastebin showing what output I get from windows, plus the 
diagnostics I've been able to think of here ->

uname output: Linux orchard 2.6.32-21-powerpc64-smp #32-Ubuntu SMP Fri

Samba4 is the latest git version.

Uhm.. Other than that, I don't know what to tell you, shout me if you 
need any more information.  I'm not including logs as there's nothing 
untoward in them.
