Disable krb5 telnetd authentication

[J. K. Cliburn]

Can someone please tell me how to configure /usr/kerberos/bin/telnetd to 
turn off kerberos authentication?  I'm starting telnetd within xinetd 
with the following /etc/xinetd.d/krb5.telnet file:

[root at petrel xinetd.d]# cat krb5-telnet
# default: off
# description: The kerberized telnet server accepts normal telnet 
sessions, \
#              but can also use Kerberos 5 authentication.
service telnet
{
         flags           = REUSE
         socket_type     = stream
         wait            = no
         user            = root
         server          = /usr/kerberos/sbin/telnetd
         server_args     = -a off -X KERBEROS_V5
         log_on_failure  += USERID
         disable         = no
}

Unfortunately, whenever I attempt to establish a login session, the 
server still attempts to authenticate to a kdc server.
