Fellows, I´m running squid 2.5.STABLE9 on a Fedora 4 server, with ntlm auth against Microsoft Active Directory, using pass-through authemtication. The problem is that, if we have some visitor (i.e., someone who did not logon on the Active Directory domain and/or whose machine is not a domain member) on my network who tries to access the Internet, Squid simply shows the message "Access denied.", giving no oportunity to the user to inform his username/password. I´d like, in that case, the user to be asked for a valid username and password. In other words, if the pass-through auth fails, the browser would show an logon dialog asking for user credencials. The auth config portion of my squid.conf follows: ============================================================================ auth_param ntlm program /usr/lib/squid/ntlm_auth DOMAIN/domain_controller auth_param ntlm children 5 auth_param ntlm max_challenge_reuses 0 auth_param ntlm max_challenge_lifetime 2 minutes auth_param ntlm use_ntlm_negotiate off ============================================================================ Could anyone give me some advice on that? Thanks a lot! Best regards, Luis Talora
