I'm having a problem getting NTLM authentication working between Squid 2.5STABLE4 and Samba 3.0.0 running on Linux 2.4.18. I've read the archives, faq, how-to, walk-thru, etc, and believe I have everthing correctly configured. I'm using the helper that is part of Samba 3.0, not the Squid helper. Basic authentication works fine with the helper, but I cannot get ntlmssp working.

I set group read,execute access to the winbind pipe directory and full read,write,execute on the pipe itself.
drwxr-x--- 2 root squid 72 Oct 27 21:21 winbindd_privileged/


srwxrwxrwx 1 root root 0 Oct 27 21:21 pipe=

I have samba configured with ads but am not using it. I joined the domain with rpc and am using security=domain in smb.conf.

The wbinfo commands work fine:
#wbinfo -t
checking the trust secret via RPC calls succeeded

#wbinfo -a TSTDOM\\testuser%testpass
plaintext password authentication succeeded
challenge/response password authentication succeeded

I can also authenticate successfully with the helper from the command line:
#ntlm_auth --username testuser --password testpass
NT_STATUS_OK: Success (0x0)

However, when I try to use ntlm authentication from a browser I get this in cache.log:
[2003/10/28 10:43:41, 10] utils/ntlm_auth.c:manage_squid_request(1061)
Got 'YR' from squid (length: 2).
[2003/10/28 10:43:41, 10] utils/ntlm_auth.c:manage_squid_ntlmssp_request(312)
got NTLMSSP packet:
[2003/10/28 10:43:41, 10] utils/ntlm_auth.c:manage_squid_ntlmssp_request(322)
NTLMSSP challenge


The browser gets the Squid Cache Access Denied error page. This happens with both IE 6.0 SP1 and Mozilla 1.5.
