Hello, I'm still using Squid 2.5 Stable3 under Fedora Core 1. (I will change it in about three months ;-) I'm using the LDAP_AUTH helper, but after each html- element (eg after each picture), I have to reauthenticate in my Browser. (IE6, Mozilla Firefox) Now I want to know, if I made a mistake in Squid.Conf or if it's a known bug of Stable 3. Here is the ACL- Part of squid.conf: (I hope, it's not too much) cache_peer cache001.xxx.de parent 8080 0 no-query login=PASS auth_param basic program /usr/lib/squid/squid_ldap_auth -u xxx xxx.de auth_param basic children 3 auth_param basic realm Squid Firma auth_param basic credentialsttl 2 hours acl noauth dstdomain "/etc/squid/squid.noauth" acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl CONNECT method CONNECT acl porn url_regex "/etc/squid/porn.txt" acl noporn url_regex "/etc/squid/noporn.txt" acl AllUsers proxy_auth REQUIRED acl FullAccess proxy_auth "/etc/squid/id_fullaccess" acl boss proxy_auth "/etc/squid/id_boss" acl staff proxy_auth "/etc/squid/id_staff" acl service dstdomain "/etc/squid/squid.service" acl free_domains dstdomain "/etc/squid/squid.free_domains" acl verbund dstdomain "/etc/squid/squid.verbund" acl free_tcpip dst "/etc/squid/squid.free_tcpip" acl no_download urlpath_regex -i "/etc/squid/squid.no_download" acl download proto FTP acl SSL method CONNECT http_access allow manager localhost http_access deny manager http_access allow noauth http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access deny porn !noporn http_access allow FullAccess http_access deny no_download http_access allow AllUsers service http_access allow verbund staff http_access allow free_tcpip staff http_access allow free_tcpip boss http_access allow free_domains boss http_access deny all
