Hello Henrik,

I'm using ntlm_auth on WINNT4.0 domain controller not
winbind. while trying to browse, only error results.
I'm getting following messages(errors) in cache.log.

ntlm-auth[672](ntlm_auth.c:255): moving on to next
controller

and in access.log ,i'm getting TCP_DENIED/407.
Don't know what may be the problem.

Thansk...

Your Squid server does not seem to know the address of your selected NT
login servers.. It needs to know these by name.

Can you ping the servers by their netbios name? If not, add them to your
/etc/hosts file...

Hello Henrik,

Thansk for your reply. I can able to ping.
I've already added netbios anme in /etc/hosts file.
But in squid.conf, when i added ip(domain
controller)as
auth_param ntlm program
/usr/local/squid/libexec/ntlm_auth
domainame/172.16.1.3

ntlm_auth won't works...same error in both log files
as in previous mail.

once when i added domaincontrollername instead of IP,
ntlm_auth works fine(able to access pages) with
following error in cache.log file.

auth_param ntlm program
/usr/local/squid/libexec/ntlm_auth
domainame/domaincontroller name

cache.log shows..

......

what may be wrong?

Thansk and Regards,
