I think I found the problem, I changed the return value of the
Curl_http_input_auth function in http.c from CURLE_OK to
CURLE_LOGIN_DENIED. Now my ftp app works without any problems for
incorrect proxy username/password. But I'm not sure what else this
change might affect, it is probably a hack for my specific need (proxy
auth). I would appreciate some input on this.
