Squid cannot authenticate to a cache_peer using NTLM. It can only do Nagotiate/Kerberos to the parent proxy, and only when "login=NEGOTIATE" is added (with or without a named keytab file). NOTE: 'connection-auth=on' is about allowing the browser to use NTLM or Negotiate/Kerberos through the cache_peer. It needs to also have "login=PASSTHRU" if that peer is a proxy (as opposed to a web or Exchange server).
