>Description:

Kerberos v5 telnetd does not work.

>How-To-Repeat:

I have downloaded the binaries from the MIT webpage and installed them under
/usr/local.  The telnetd daemon was copied from /usr/local/sbin to /usr/lbin.
I changed directories to /usr/local/sbin and used the ktutil program to convert
my Kerberos v4 srvtab to a Kerberos v5 srvtab:

# pwd            
/usr/local/sbin
# ./ktutil
ktutil:  rst /etc/athena/srvtab
ktutil:  wkt /etc/krb5.keytab
ktutil:  exit

Next, I moved to /usr/local/bin and attempted to telnet back into my
workstation:

julia 77: ./telnet -axf julia
Trying 18.63.0.32...
Connected to julia.mit.edu (18.63.0.32).
Escape character is '^]'.
Waiting for encryption to be negotiated...[ Kerberos V5 refuses authentication because telnetd: krb5_rd_req failed: Unknown Key table type ]
[ Kerberos V5 refuses authentication because telnetd: krb5_rd_req failed: Unknown Key table type ]
[ Kerberos V5 refuses authentication because telnetd: krb5_rd_req failed: Unknown Key table type ]

Authentication negotation has failed, which is required for
encryption.  Good bye.


I also tried to telnet into a private athena workstation running Kerberos v5:

julia 86: ./usr/local/bin/telnet anita
./usr/local/bin/telnet: Command not found.
julia 87: pwd
/usr/local/sbin
julia 88: /usr/local/bin/telnet -axf anita
Trying 18.63.0.243...
Connected to anita.mit.edu (18.63.0.243).
Escape character is '^]'.
Waiting for encryption to be negotiated...[ Kerberos V5 accepts you as ``gsin@ATHENA.MIT.EDU'' ]
done.
What you type is protected by encryption.

It seems to work fine.
