Hi Everyone; I'm in the process of configuring Squid on a linux box. I've successfully configured Samba (3.0.10.0) to communicate with my Windows 2003 domain. I am able to authenticate using both plain-text and ntlm authentication using the wbinfo tool. I also receive a good reply when using 'wbinfo -p'. I've compiled squid (2.5 STABLE-8) with ntlm and basic helpers, everything seemed to go well and Squid has been installed into its default path (/usr/local/squid/). What I am attempting to do is test the nt_auth helper outside of Squid before configuring Squid to use NTLM authentication and I am receiving the error mentioned in the subject line. Can anyone think of any reason why I would be receiving that error if everything checks out okay with winbind? I'm sure that it's something simple that I'm missing... Thanks!
