CISCO and kerberos

[jarek]

Hi all!

I'd like to configure CISCO Catalyst to use kerberos against AD server 
W2008. I'd like to login to cisco using ticket and telnet.krb5 from 
krb5-clients package. When I'm trying telnet.krb5 -a -f cisco_ip, I'm 
getting:

[ Kerberos V5 refuses authentication ]
kerberos_server_auth:	Couldn't authenticate client from test-nms.test.local.

What can be wrong ?

Has someone working example of CISCO config for such scenario ?

J.
