CURLOPT_KRBLEVEL(3)        Library Functions Manual        CURLOPT_KRBLEVEL(3)

NAME
       CURLOPT_KRBLEVEL - FTP kerberos security level

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_KRBLEVEL, char *level);

DESCRIPTION
       Pass a char pointer as parameter. Set the kerberos security level for
       FTP; this also enables kerberos awareness. This is a string that should
       match one of the following: &'clear', &'safe', &'confidential' or
       &'private'. If the string is set but does not match one of these,
       'private' is used. Set the string to NULL to disable kerberos support
       for FTP.

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