Captive Portal authentication in Squid Proxy Server does not work

[kychou]

I have configured Authentication Method to "Captive Portal" in Squid Proxy Server -> Authentication
But it does not work, squid cannot get current user and deny access.
The version is 2.4.4-RELEASE (amd64)

Captive Portal authentication has been migrated to the user manager in 2.4.4. That option probably no longer makes sense.
