CURLOPT_KRBLEVEL(3)        curl_easy_setopt options        CURLOPT_KRBLEVEL(3)

NAME
       CURLOPT_KRBLEVEL - set FTP kerberos security level

SYNOPSIS
       #include <curl/curl.h>

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

DESCRIPTION
       Pass a char * 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 doesn't match one of these,
       'private' will be 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.

DEFAULT
       NULL
