[Samba] NTLMv2, Samba, and Squid

[Darren Maskowitz]

Here is the problem: I'm setting up a new squid proxy server with
authentication via Samba and NTLM because the old one died suddenly.
The new one is up and running and i have it working; mostly. The
kicker is the 2 employees testing Vista (myself and my supervisor)
could not authenticate against the server. I say could because through
a variety of testing and some lucky reading I found the cause of the
problem to be that by default Windows Vista uses NTLMv2 only, and when
I change the setting to LM & NTLM using NTLMv2 for negotiation it all
works. The old proxy server allowed us ot authenticate using NTLMv2,
and that is the goal of this question: what am I missing in my
configuration? Here's a dump of smb.conf taken via a testparm:

[global]
        workgroup = EDMCOMPUTRONIX
        realm = COMPUTRONIX.COM
        server string = CX Canada's SQUID Web Proxy

        preferred master = No
        domain master = No
        dns proxy = No
