Problems with kerberized telnetd and telnet

[Kenneth Stephen]

Hi,

	I'm using the Debian GNU/Linux version of kerberized telnetd and
telnet and am trying to do kerberos based telnet logins. The steps I
follow are (1) kinit (2) telnet -F <telnet server>, but I get a failure.
Here are the gory details :

ken at sid:~$ klist
Ticket cache: FILE:/tmp/krb5cc_1000
Default principal: y2kmvs at ebiz.austin.ibm.com

Valid starting     Expires            Service principal
01/13/03 13:36:15  01/13/03 23:35:38  krbtgt/ebiz.austin.ibm.com at ebiz.austin.ibm.com


Kerberos 4 ticket cache: /tmp/tkt1000
klist: You have no tickets cached

ken at sid:~$ telnet -F -k ebiz.austin.ibm.com ebiz.austin.ibm.com
Trying A.B.C.D...
Connected to ebiz.austin.ibm.com (A.B.C.D).
Escape character is '^]'.
telnetd: No authentication provided.
Connection closed by foreign host.

	An ethereal trace shows the following exchange :

		New Environment Option

		Terminal Type

server --> client
	Data:
		telnetd: No Authentication provided. \r\n

....and the server initiates a connection close.

	telnetd is being started with a '-a user' option. Is this not the
right option for Kerberos authentication? Why does the client claim that
it wont do authentication?

Thanks,
Kenneth
