I would try adding the first couple lines auth_param and When I first set it up following the link I posted, I used: acl myusernameUser proxy_auth myusernameUser http_access allow myusernameUser which didn't work until I switched it to acl myusername proxy_auth myusername http_access allow myusername My latest setup works as posted using ncsa_users, which should only allow a user in the passwd file. Wish I could help more, just going forward blindly on my own as well.
