The krb5-appl telnet has not been updated and is unlikely to be updated.
I believe that Jeff Altman added support for Kerberos authentication to
some telnet distribution that had TLS support, and that may even be
securely bound into the authentication.
I don't know which product that was or whether that happened.
Most of the world is using RFC 4462 Kerberized Ssh at this point.
