We fixed this in SuSE when I was working for Novell by the
use of helpers in firefox that would invoke the ntlm_auth
code for old IIS servers that only use NTLM instead of
kerberos. Winbindd has to have a credential cache set up
from login in order to create the NTLMSSP blobs for firefox.
Note sure of the state of that code integrated into the
firefox shipped by Ubuntu - I know it's in the openSuSE

Nautilus could use the same code (although I believe that
uses krb5 tickets by preference).

You might want to raise this one with launchpad. I can
help them integrate the same code that was done for
SuSE is they haven't already done it.

The argument to ntlm_auth is ""ntlmssp-client-1"
