CURLOPT_LOGIN_OPTIONS

Section: C Library Functions (3)
Updated: 202-0-19
Index Return to Main Contents

NAME

CURLOPT_LOGIN_OPTIONS - login options

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_LOGIN_OPTIONS, char *options);

DESCRIPTION

Pass a char pointer as parameter, which should be pointing to the null-terminated options string to use for the transfer.

For more information about the login options please see RFC 2384, RFC 5092 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.

Since 8.2.0, IMAP supports the login option "AUTH=+LOGIN". With this option, curl uses the plain (not SASL) LOGIN IMAP command even if the server advertises SASL authentication. Care should be taken in using this option, as it sends your password in plain text. This does not work if the IMAP server disables the plain LOGIN (e.g. to prevent password snooping).

The application does not have to keep the string around after setting this option.

Using this option multiple times makes the last set string override the previous ones. Set it to NULL to disable its use again.

DEFAULT

NULL

PROTOCOLS

This functionality affects imap, ldap, pop3 and smtp

EXAMPLE

int main(void)
{
  CURL *curl = curl_easy_init();
  if(curl) {
    CURLcode result;
    curl_easy_setopt(curl, CURLOPT_URL, "smtp://example.com/");
    curl_easy_setopt(curl, CURLOPT_LOGIN_OPTIONS, "AUTH=*");
    result = curl_easy_perform(curl);
    curl_easy_cleanup(curl);
  }
}
