[squid-users] NTLM auth with ubuntu

Hello list.

I have been trying to get NTLM authentication working with squid and winbind
under ubuntu 6.10. I can get user names and account with winbind, I can even try
  using a domain user to login and I see this in my logs.
Dec 27 13:00:06 proxy pam_winbind[6734]: user 'domainuser' granted access

The proxy works well if I have no authentication, however if I try to put
authentication in place, I get asked for the user name and password 3 time then
I get kicked out to a cache access denied page saying I cant access anything
until I authenticate to the proxy. According to what I have found on line my
setup should be correct. Any help would be appreciated.
