I have installed latest squid-dev3 and squidguard 3. I have created 2 acl profile in group acl and authentication is through captive portal. I have a issue after first user from any acl login, he is able to open the site , but the second user from the same acl or other profile gets the following error.

I think there is some error with authentication through captive portal, its working if I put static ip on terminals.
