Re: Automatic Authentication with Internet Explorer?

Unfortunately I cannot use identd because we use dhcp, and most of the PCs
are used by several people (in shifts), and several users use different PCs
every day, so there's no real relationship between an IP-address and a
user. Further, company policy sort of makes installing things like ident on
the PCs very difficult.

Squid just performs so much better than MS Proxy that it's worth waiting
for. Even if NTLM never makes it into Squid, we'd never ever consider going
back to MS Proxy.

What would be nice is if it was possible to output a page from Squid just
before it tells the browser to pull the authentication box up. That way we
could instruct our users what to do as they're used to not having to enter
a userid/password to get out. Unfortunately I have way too little
experience with Squid (yet) to be able to fix that myself.

Any suggestions?

1) The user requests a url which needs authentication
2) Squid sends out the short instruction page to the browser
3) Squid tells the browser to pull the authentication dialog box up
4) The browser pulls the authentication dialog box up on top of the
instructions page
