I am having a problem trying to use an external acl with Squid version 2.5 STABLE8 on Fedora Core 3. I have the following lines in my /etc/squid/squid.conf file: external_acl_type myAuthType %SRC /usr/lib/squid/myAuth.pl acl myAuth external myAuthType http_access allow myAuth When I start Squid, I revceive the following errors: 2005/03/22 11:54:22| ipcCreate: /usr/lib/squid/myAuth.pl: (13) Permission denied 2005/03/22 11:54:22| WARNING: myAuthType #1 (FD 7) exited I have set the permissions of the myAuth.pl file using 'chmod 4755' so I know that it should be accessible. Additionally, I know the script works since I can run it from the prompt (it simply prints the input to a file and returns 'OK'). Many thanks to anyone who can help!
