Hi, I have a simple configuration of Squid, with a acl to deny access to users that aren't authenticated. I have setup kerberos correctly as the squid server ask tickets. There is no AD, just a kerberos server, squid server and Windows XP clients. The Windows client uses Network Identity Manager (MIT) to create a ticket. I could not find a solution in the mailing list archives and other places on the internet. When I use the proxy with Firefox (3.6.10, laterst version, same on IE), I get: ERROR Cache Access Denied While trying to retrieve the URL: http://dd/ The following error was encountered: * Cache Access Denied. Sorry, you are not currently allowed to request: http://dd/ from this cache until you have authenticated yourself. A keytab file for the proxy exists (squid.keytab) and squid has read access to it. This file is created using "addprinc -randkey squid/MYNETWORK.COM" I added in the top of the /etc/init.d/squid file the following: KRB5_KTNAME=/etc/squid/squid.keyab export KRB5_KTNAME The squid configuration is as following: uth_param negotiate program /usr/lib/squid/squid_kerb_auth -d auth_param negotiate children 10 auth_param negotiate keep_alive on 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 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 acl password proxy_auth REQUIRED http_access allow manager localhost http_access deny manager http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow password http_access deny all icp_access allow all http_port 3128 hierarchy_stoplist cgi-bin ? access_log /var/log/squid/access.log squid acl QUERY urlpath_regex cgi-bin \? cache deny QUERY refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern . 0 20% 4320 acl apache rep_header Server ^Apache broken_vary_encoding allow apache cache_mgr root@localhost coredump_dir /var/spool/squid When accessing squid from Firefox/IE, I get in cache.log: 2010/09/21 11:41:12| squid_kerb_auth: Got 'YR ElRMTVNTUABBAAAAB4IIogAAAAAAAAAAAAAAAAAAAAAFASgDAAAADw==' from squid (length: 59). 2010/09/21 11:41:12| squid_kerb_auth: parseNegTokenInit failed with rc=101 2010/09/21 11:41:12| squid_kerb_auth: received type 1 NTLM token It is strange that the proxy receives NTLM messages, as it is not configured.
