I am using ubuntu 12.04 and centos 6 as virtual machine on it. I've configured squid on centos and I'm trying to access it from browsers in ubuntu. I checked using browsers in Centos also. It worked fine when I used ncsa authentication, but it is not working with mysql db authentication. I used this page to configure squid authentication using mysql (http://wiki.squid-cache.org/ConfigExamples/Authenticate/Mysql?) Here is the cache.log file [root@centos ~]# tail /var/log/squid/cache.log My squid.conf file is It worked fine with ncsa authentication. Am I doing something wrong?
