NAME

CURLOPT_LOGIN_OPTIONS - login options

SYNOPSIS

#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_LOGIN_OPTIONS, char *options);

For more information about the login options please see RFC2384, RFC5092 and the IETF draft draft-earhart-url-smtp-00.txt. CURLOPT_LOGIN_OPTIONS(3) can be used to set protocol specific login options, such as the preferred authentication mechanism via "AUTH=NTLM" or "AUTH=*", and should be used in conjunction with the CURLOPT_USERNAME(3) option. The application does not have to keep the string around after setting this option.
