Have you traced to see if the error is Samba failing, or simply the link
between Squid and the windows client failing?

It is not really possible to setup multiple copies of winbind on a
single machine, aside from a chroot(), because of the socket in /tmp.

However, winbind can be made better - I looked into the idea of having
multiple outstanding requests to the NT DC, using Samba4 as a research
tool.  This does not seem possible at this point, but we do need to keep
looking at it.  Perhaps this is why microsoft demands that their NTLM
proxy server be a BDC... (or so I understand).
