worked but for last few days it is showing error when i restart squidl. It says like "acl auth REQUIRED is wrong fatal error. authenticaion scheme is not configured properly " some thing like that. i was 100% sure i followed the same procedure what it is not working now.

Please kindly anyone show me a way to authenticate users to use proxy. Thank you very much.
