CURLOPT_KRBLEVEL - Man Page

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' 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.
