Hello, I have configured squid (2.5 STABLE6) to authenticate to a windows domain with ntlm_auth. Sometimes during navigation users receive annoiyng request for basic authentication from squid. These events are frequent increasing the number of users that access to proxy. This is the relevant part of configuration: ---------- auth_param ntlm program /usr/lib/squid/ntlm_auth DOMAIN/CONTROLLER auth_param ntlm children 15 auth_param ntlm max_challenge_reuses 5 auth_param ntlm max_challenge_lifetime 60 minutes auth_param ntlm use_ntlm_negotiate off acl DomainAuth proxy_auth REQUIRED http_access deny !DomainAuth ---------- Can you help me? Regards, Marco
