Squid NTLM authentication against Windows 2008 R2 AD

[Mike Diggins <mike.diggins@xxxxxxxxxxx>]

My organization is about to upgrade our Windows 2000 AD to Windows 2008 
R2. I use winbind in Samba 3.0.30 with Squid and NTLM to authenticate my 
users. Today I joined my test Squid server to the Windows 2008 R2 domain 
for testing. Joining the domain worked but authentication using the Samba 
tools (ntlm_auth/wbinfo) does not. I've read this may be a known problem. 
I've also read that upgrading to Samba 3.3x might fix it. Can anyone 
confirm this is a known issue and what options there are to fix it?

I understand this isn't a Squid problem, but I figured someone here must 
of run into this by now.
