                     31: .SH DESCRIPTION
                     32: Pass a char * as parameter. Set the kerberos security level for FTP; this also
                     33: enables kerberos awareness.  This is a string that should match one of the
                     34: following: \&'clear', \&'safe', \&'confidential' or \&'private'.  If the
                     35: string is set but doesn't match one of these, 'private' will be used. Set the
                     36: string to NULL to disable kerberos support for FTP.
                     37: 
                     38: The application does not have to keep the string around after setting this
