Hello squid users,
I can't seem to get the ntlm to work on the following setup:
Debian 4.0 etch
Squid Cache: Version 2.6.STABLE5
Microsoft Windows Server 2003 SP2
Kerberos environment OK: wbinfo -t, -u and -g work fine
Using ntlm_auth from Samba Winbind 3.0.24-6etch9
squid.conf looks like this:
http_port localhost:3128
icp_port 0
htcp_port 0
refresh_pattern -i \.flv$ 10080 90% 999999 ignore-no-cache

The authentication works fine with the --helper-protocol=squid-2.5-basic
but with the ntlm protocol the following appears in the log files. Can
someone shed some light on this ? I don't know what to investigate
further as there is no explicit error message. It seems as if the NTLM
protocol starts fine but then stops because one of the parties does not
send what it's supposed to. I've tried using the ntlmauth bundled with
Squid but that doesn't solve the problem.

NTLMSSP challenge
Isn't the NTLM negotiation supposed to be longer ?
I think this is the same problem as in
http://www.squid-cache.org/mail-archive/squid-dev/200708/0167.html but
the answer to that question does not give a solution. Has someone solved
this ?
Thanks,
Jerome Steunenberg
