squid2.2S4 and authentication...

[Soren Aalto <soren@xxxxxxxxxxxxxxx>]

I have a copy of Squid2.2S4 here that is the proxy for
our student labs.  Suddenly it tells everybody that they
aren't authenticated and all attempts to give a username/password
fail.

I was suspicious as I have a lot of wierd stuff woven into
this -- the authenticator program is an SUIDed copy of ncsa_auth
that autheticates against /etc/shadow (no lectures please),
and then there is a fancy redirector that talks to other
stuff I don't even want to go into...

Whatever.

However, when I turn on tracing of the password stuff, the
username/password is getting handed to the authenticator
OK & being checked properly.  But then squid hands back a
407/Proxy auth req'd header like so:

GET http://www.uct.ac.za/ HTTP/1.0

HTTP/1.0 407 Proxy Authentication Required
Server: Squid/2.2.STABLE4

The thing that wierds me out -- it does this even though
I have taken out the ACL that asks for authentication and
have disabled all of the other stuff.

I have no idea what is going on.  I have another copy
of 2.2S4 running for the staff LAN and there don't seem
to be any problems there, although there isn't the same
goofy redirector stuff going on and I am authenticating
against a file that isn't /etc/shadow.

I'm just hoping somebody has seen something like this
before?
