Have you contacted Apple and logged a bug with this ?

I know that Apple test with Samba before release, but I'm
not sure what configurations they test. Raise it with
Apple and if it turns out to be a Samba problem come
back to the list and we'll fix it on our side. Ensuring
Macs work against Samba is a very high priority for us.
