Log in on gssftp server without the need of using Kerberos authentication:

-bash-3.00$ vi /etc/xinetd.d/gssftp
# default: off
# description: The kerberized FTP server accepts FTP connections \
#              that can be authenticated with Kerberos 5.
service ftp
{
disable = no
flags           = REUSE
socket_type     = stream
wait            = no
user            = root
server          = /usr/kerberos/sbin/ftpd
#server_args    = -l -a
server_args     = -l
log_on_failure  += USERID
}

I had to use it on RedHat5.
