Does anybody know of an open source solution that does HTTP proxying whilst providing NTLM authentication? I've tried to set up apache + mod_proxy + mod_ntlm. For HTTP GETs it works fine , i.e. the user is asked for a username+password and then the proxy retrieves the file. However, for HTTP CONNECTs this does not work. Remove mod_ntlm and apache + mod_proxy works fine with HTTP CONNECT.
Do you need to authenticate client to proxy or to destination server? For proxy authentication (= Apache in your case) you just say
and that will require clients to authenticate also when using
