As I mentioned to Andreas on IRC, I'm handling this with Microsoft
directly, as I'm working with them next week at our annual AD interop.
They will get back to us when they know the official answer.

They went to great lengths to ensure that Samba 3 domains were supported
in Windows 7, so I want to give them a chance to get us an official
response before we pursue this further.  Getting them a copy of your
network trace may assist if they have trouble reproducing the situation,
but currently that hasn't been raised as a blocker.

Even if we find a way to make the join appear to work, we are asking the
question more broadly: because we want to know what else we may have
lost, such as the loss of NT system policies in Windows 7.
