You could just configure basic authentication using the Samba ntlm_auth helper. It'll then still authenticate against active directory, but it wouldn't use NTLM between the browser and squid to do it. (Some of the caches at work have this setup but I don't think anyone's using it yet. I'll try it out today.) Adrian
