As outlined before.

http_access allow/deny non_matching_proxy_auth_acl -> ignored
http_access deny proxy_auth_acl -> 407(401)
http_access deny other_acl -> 403

Not yet fully logged in, touching a proxy_auth ACL -> 407(401)

ACL processing:

User not matched by the proxy_auth ACL -> false (0).

Question: How to generate scheme challenges in the first case where the
user is authenticated but not authorized.

Answer: authenticateFixHeader needs to be aware that the header fixup is
due to authorization failure, not authentication failure, and then force
the client to send new credentials even if the current ones are valid.
This is the call to authenticateFixHeader from errorpage.c where the
last argument is 1 (currently named "internal", should probably be
"unautorized" or something similar...).
