DESCRIPTION

14       Pass  a  char  * as parameter. Set the kerberos security level for FTP;
15       this also enables kerberos awareness.  This is  a  string  that  should
16       match  one  of  the following: 'clear', 'safe', 'confidential' or 'pri‐
17       vate'.  If the string is set but does not match one of these, 'private'
18       will  be  used.  Set the string to NULL to disable kerberos support for
19       FTP.
20
21       The application does not have to keep the string around  after  setting
22       this option.
