Yes. Multiple authentication methods, triggered from multiple sources, going via multiple paths can be confusing. Squid auth_param elided, which leaves: "A user name and password are being requested by ..." == basic challenge by ISA. "Enter user name and password for ..." == integrated/NTLM challenge by ISA. I'm now thinking we have two distinct configurations for Squid: Basic Auth (only) passed back cache_peer ... login=PASS connection-auth=off NTLM Auth (only) passed back: cache_peer ... connection-auth=on Which appear to be non-compatible auth methods at present. What happens if you re-enable the connection-auth on https_port and remove the login=PASS from cache_peer?
