Hi all, I'm trying to make squid works with my Samba PDC. The command: root@squid~# ntlm_auth --helper-protocol=squid-2.5-basic xxx+root ##### OK But The squid always pop-up for a username password, no matter how many different users/passwords I try. Here is: auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 30 auth_param ntlm max_challenge_reuses 0 auth_param ntlm max_challenge_lifetime 2 minutes auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param basic children 5 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 2 hours Thanks in advance.
