Hello! I have set up a Squid 2.6v6 STABLE16 server in a RHEL4. Our company is under MS Active Directory and the squid server authenticates users against AD successfully, but we have a problem, users that are not in AD (we are still migrating our system) cannot navigate. I have written this in the squid.conf file auth_param basic program /usr/libexec/squid/ncsa_auth /usr/local/squid/etc/passwd (thinking about users not in AD) auth_param ntlm program /usr/bin/ntlm_auth -helper-protocol=squid-2.5-ntlmssp (For users in AD) When a user in AD opens Internet Explorer or Mozilla Firefox automatically is authenticated ( I took a look at cache.log) and is able to navigate. When a user not in AD opens Internet Explorer or Mozilla, a small window is prompted asking for user and password, I type a valid user and pass that is in the file but it does not work. This password files has been created with Webmin, another file following some guides. I have tried both pass files but no success with that. Please I would like to know how to manage 2 different types of authentication, the firs for users in AD and the seconds for users not in AD. Thank you very much.
