Try on a pfsense with squid 3.4.10 an ntlm-authentication. In my suid.conf: /auth_param ntlm program /usr/local/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp/ When I restart squid I always see this in my syslog: Jan 15 13:38:35 pf4322 squid: auth_param ntlm program /usr/local/bin/ntlm_auth: (2) No such file or directory But the path to ntlm_auth is right! I can start /usr/local/bin/ntlm_auth from the shell. So what file or directory does he means? Thanks very much in advance Alex -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/ntlm-No-such-file-or-directory-tp4669085.html Sent from the Squid - Users mailing list archive at Nabble.com. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
