Squid HTTPS transparent Authentication not happening

[rackg]

I have setup Squid proxy with Transparent HTTPS, however i am unable to get the proxy to work with user authentication. When the clients behind firewall could get access  to internet without any authentication (local user) . Kindly help me to fix this.

I have validated the following.

1. Local user has been created
2. Firewall authentication has been set to Local Database .

from the source (squid) http://wiki.squid-cache.org/Features/Authentication#Authentication_in_interception_and_transparent_modes

Authentication in interception and transparent modes
Simply said, it's not possible to authenticate users using proxy authentication schemes when running in interception or transparent modes. See SquidFaq/InterceptionProxy for details on why.

Maybe a captive portal is more suitable for your needs.
