You have to get the ticket for the service you try to contact (the name 
of service is defined by -s switch in client/server commandline). The 
ticket must exist in the kerberos cache on client host otherwise the 
client try to contact KDC to get this ticket. In your case the client 
can not do this.  Either Kerberos realm is not configured on client host 
or KDC ports are blocked by some sort of firewall.
Hope this helps.
