Hello. I have been following the steps provided in the HOWTO: Web Filtering On Squid 3 With QuintoLabs Content Security 1.4 And Windows Active Directory Integration (http://www.howtoforge.com/web-filte...4-and-windows-active-directory-integration-p2) But I get presented with a login box for access to the proxy. I type in the details, of any AD account but it just pops up again.. Everything seems to have gone OK and I haven't had any specified errors... I am a quite a linux noob but have managed to work through this little project. So any help would be greatly appreciated. smb.conf Code: [global] workgroup = PIT1 realm = PIT1.LOCAL server string = Samba Server Version %v security = ADS log file = /var/log/samba/log.%m max log size = 50 cups options = raw kerberos method = dedicated keytab dedicated keytab file = /etc/krb5.keytab [homes] comment = Home Directories read only = No browseable = No [printers] comment = All Printers path = /var/spool/samba printable = Yes browseable = No squid.conf Code: # Setup NEGOTIATE authentication for Active Directory with Kerberos # auth_param negotiate program /usr/lib/squid/negotiate_kerb_auth -s HTTP/proxy auth_param negotiate children 10 auth_param negotiate keep_alive on # # to see the negotiator log messages in the /var/log/squid/cache.log uncomment # debug_options 29,9 and pass additional -d parameter to negotiate_kerb_auth # acl auth proxy_auth REQUIRED # # Recommended minimum configuration: # acl manager proto cache_object acl localhost src 127.0.0.1/32 ::1 acl to_localhost dst 127.0.0.0/8 0.0.0.0/32 ::1 # Example rule allowing access from your local networks. # Adapt to list your (internal) IP networks from where browsing # should be allowed # acl localnet src 10.0.0.0/8 # RFC1918 possible internal network acl localnet src 172.16.200.0/24 # RFC1918 possible internal network # acl localnet src 192.168.0.0/16 # RFC1918 possible internal network # acl localnet src fc00::/7 # RFC 4193 local private network range # acl localnet src fe80::/10 # RFC 4291 link-local (directly plugged) machines acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT # # Recommended minimum Access Permission configuration: # # Only allow cachemgr access from localhost http_access allow manager localhost http_access deny manager # http_access allow localnet # Deny requests to certain unsafe ports http_access deny !Safe_ports # Deny CONNECT to other than secure SSL ports http_access deny CONNECT !SSL_ports # We strongly recommend the following be uncommented to protect innocent # web applications running on the proxy server who think the only # one who can access services on "localhost" is a local user # http_access deny to_localhost # # INSERT YOUR OWN RULE(S) HERE TO ALLOW ACCESS FROM YOUR CLIENTS # http_access deny !auth http_access allow auth # Example rule allowing access from your local networks. # Adapt localnet in the ACL section to list your (internal) IP networks # from where browsing should be allowed # http_access allow localnet # http_access allow localhost # And finally deny all other access to this proxy http_access deny all # Squid normally listens to port 3128 http_port 3128 # We recommend you to use at least the following line. hierarchy_stoplist cgi-bin ? # Uncomment and adjust the following to add a disk cache directory. #cache_dir ufs /var/spool/squid 100 16 256 # Leave coredumps in the first cache dir coredump_dir /var/spool/squid # Add any of your own refresh_pattern entries above these. refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern -i (/cgi-bin/|\?) 0 0% 0 refresh_pattern . 0 20% 4320 visible_hostname proxy.pit1.local icap_enable on icap_preview_enable on icap_preview_size 4096 icap_persistent_connections on icap_send_client_ip on icap_send_client_username on icap_service qlproxy1 reqmod_precache bypass=0 icap://127.0.0.1:1344/reqmod icap_service qlproxy2 respmod_precache bypass=0 icap://127.0.0.1:1344/respmod adaptation_access qlproxy1 allow all adaptation_access qlproxy2 allow all I've probably missed something really simple...
