Hi, Please excuse my ignorance on this one, but I cant seem to get this working correctly. What im trying to do is run an LDAP authenticator for anyone that isnt part of the local network (i.e. remote cache from home or something). I am also transparently redirecting all traffic inbound on an interface to the cache. Now there are two problems that I am stumped with. The relevant parts of my squid.conf file: auth_param basic program /usr/local/etc/ldap_auth.sh auth_param basic children 5 auth_param basic realm my.server.net Cache LDAP Authentication auth_param basic credentialsttl 2 hours http_port 3128 transparent acl LDAP proxy_auth REQUIRED acl ALLOWIP src "/usr/cache/lists/allowip.list" http_access deny !Safe_ports http_access deny CONNECT !SSL_ports http_access allow ALLOWIP http_access allow LDAP http_access deny all Okay. So the first problem is in cache.log i have the following: 2007/04/30 13:16:40| strtokFile: /usr/cache/lists/allowip.list not found 2007/04/30 13:16:40| aclParseAclLine: WARNING: empty ACL: acl ALLOWIP src "/usr/cache/lists/allowip.list" Now that file exists fine: [root@my] ~ # ls -l /usr/cache/lists/allowip.list -rwxrwxrwx 1 root www 44 Apr 30 12:57 /usr/cache/lists/allowip.list [root@my] ~ # And the contents: 10.10.0.0/255.255.0.0 10.11.0.0/255.255.0.0 Any idea why squid wont read it? Then the second problem is that for the LDAP auth I am getting this in the cache.log when someone is transparently redirects and their ip isnt in the ACL: aclAuthenticated: authentication not applicable on transparently intercepted requests. Now, I have done transparent auth using LDAP before and its only since I upgraded to 2.6 from 2.5 that this started. The transparent cache works fine if I dont have any authenticators running or if I point to it. I am running squid 2.6 Stable 10. The authenticators work fine if I point to the cache so its just the combination of the two thats causing the problem. Thanks in advance... Ian
