+# NAME
+
+CURLOPT_KRBLEVEL - FTP kerberos security level
+
+# SYNOPSIS
+
+~~~c
+#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.
