It's a recent Squid version - 3.5.20 on CentOS 6, built from the SRPM kindly provided by Eliezer.

There was nothing more in the log previously posted at the point the 407 response was returned to the client.

That log did have a lot of other stuff in it though.  Using a much simpler squid.conf (attached), I tested for differences in authenticated vs unauthenticated requests, when "http_reply_access deny all" is in place.  When credentials are supplied, a http/403 (forbidden) response is provided, as you would expect.  But when credentials are not supplied, a http/407 response is provided.  The divergence seems to start around line 31 in cache_noauth.log:

Checklist.cc(63) markFinished: 0x331e4a8 answer AUTH_REQUIRED for AuthenticateAcl exception

Perhaps when answer=AUTH_REQUIRED (line 35), http_reply_access is not checked?  Another difference is that Acl.cc(158) reports async when an authenticated request is in place, but not otherwise.  If someone could give me some pointers where to look in the source, I can start digging to see if I can find out more.
