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  *  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.

DEFAULT

       NULL

PROTOCOLS
