NTLM is the only method whereby the browser automatically logs in to the
proxy using the same login details as used for logging in to the Windows
workstation.

fakeauth is a NTLM verifier, accepting any login as valid.

The other authentication schemes only provides automatic login via the
"Save this login" function in your browser login box.

The SMB ntlm helper (Squid ntlm_auth) allows you to query any Windows file
server who is member of the domain to verify the login. But it requires
the proxy to be allowed to reach the SMB port on some Windows server in
the domain.

Not easily, as the user automatically gets logged in in the first place.

This is possible only if the actual user is not member of any of the
groups, forcing him to log in as some other user (in his browser) to
access the web.
