I'm running Squid 3-STABLE10 and Samba 3.2.4. My auth_param statement looks like: auth_param ntlm program /usr/local/squid/libexec/ntlm_auth -b dc01 dc02 dc03 authentication is working but in the past there was a "helper-protocol" setting under Squid 2 along the lines of: /usr/local/samba/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp. Is there a equivalent for Squid 3? Thanks in advance, Mark Krawec mark@xxxxxxxxxx
