I have defined this acl's in my squid.conf file. What i would like to access the user id temp from only one computer. If someone tries to authenticate using that user id from another pc it must be denied. What am I doing wrong? auth_param basic program /usr/local/squid/bin/auth/squid_auth_ldap -f /usr/local/squid/bin/auth/squid_auth_ldap.conf auth_param basic children 5 acl USERS proxy_auth REQUIRED acl dlid proxy_auth temp acl comp src ipnum/netmask http_access allow comp dlid http_access allow USERS http_access deny all Carinus
