Hello, is my first post in the list, I wonder if someone already went through this problem. I'm using "Squid 2.7.STABLE3" with NTLM authentication. Windows users authenticate without problems, but when logged in with User "administrator" can not access the Internet, is how he had managed to authenticate the user "administrator" How would this situation for users who are not in the field? Is that any way around this situation? below my configuration: auth_param ntlm program /etc/squid/squid/ntlm_auth brk/dcbrk auth_param ntlm children 5 auth_param ntlm max_challenge_reuses 0 auth_param ntlm max_challenge_lifetime 2 minutes Thanks, any idea will be very useful!
