I have followed the instructions in section 23.5 on http://www.squid-cache.org/Doc/FAQ/FAQ-23.html
I configured Samba Version 3.0.4 --with-winbind I have smbd, nmbd, and winbindd running and have tested winbindd user authentication successfully I built squid: Squid Cache: Version 2.5.STABLE5-20040707 configure options: --enable-auth=ntlm,basic --enable-external-acl-helpers=wbinfo_group and tested it without authentication - works fine. I tested the Test the Samba-3.x helper - works fine I added the relevant auth_param's and adjusted the acls in squid.conf - no go :( I use IE6.0 and it pops up a username/password prompt. I enter in my credentials - no go. I enter in my credentials with domain\username - no go. (on an MS proxy 2.0 server with authentication it works fine - so I am doubting it is browser related) I know I must be missing something simple, but I just can't spot it. My smb.conf and the relevant parts of my squid.conf are attached - server names and IPs have been altered for privacy reasons. If someone could help me here I'd really appreciate it.

# This is the main Samba configuration file. You should read the # smb.conf(5) manual page in order to understand the options listed # here.
