Authenticating Server: 2003 with Active Directory Enabled
Squid Server: FreeBSD 5.1
Samba: 3.0.7,1
Other package info in package list at bottom.
The DNS server is on the 2003 Server with the proper kerberos and ldap
entries in the DNS server. (Passes Active Directory DNS utility tests)
Responses are sent in LM, NTLM, &NTLM2 when negotiated.
Signing requirements are not configured. (Choices: Enable, or not
configured).
Have read, and followed to best of my ability the squid FAQ and
winbind/nmb/samba man pages. Things that work: All of the command line
based tests work, as you will see when you look below. But when I try to
authenticate with a browser I get denied, and the following info in
cache.log and log.winbindd. If I modify the permissions on
/var/db/samba/winbindd_privileged, that breaks the wbinfo tests saying that
the permissions on that file are incorrect.
Note: when I went to build samba --with-ads on freebsd it complaind about
KRB5 and asked for HEIMDAL instead...so I am actually using HEIMDAL not
KRB5, as Samba refused to compile with KRB5 but compiled fine with HEIMDAL.
Squid works great unauthenticated, but fails all auth tests when using an
actual browser. The squid-helper passes basic auth tests from the command
line, but when using a browser such as netscape which should use BASIC auth
mode, it denies with the same messages in the logs as IE failing on
challenge/response.

Not Sure which files needed to modify for ntlm_auth to work. Have tried
passwd and login by adding lines listed in squid FAQ. I am using a newer
version of pam that uses /etc/pam.d/service for authentication directions.
Do I need to create a new auth file called ntlm_auth?
