1. Introduction
Kerberos Version 5 [RFC4120] is a trusted third-party authentication
system. Each organization wishing to use Kerberos establishes its
own "realm", and each client is registered as part of that realm. At
least one Key Distribution Center (KDC) is required for the operation
of a Kerberos realm.
When a client wishes to communicate with, and be authenticated to, a
Kerberos application server (also a client of the KDC), the client
identifies itself, and its realm, to the KDC and acquires a
credential from the KDC. The client then presents the credential to
the Kerberos application server, which can use the credential to
authenticate the client. The client needs to know at least one IP
address for a KDC in order to initiate this process.
One example of the application of this protocol is as follows. A
student might want to use a shared, public workstation, one that is
