An Example of the Operation of the Client .............11 Sakane & Ishiyama Standards Track [Page 2] RFC 6784 Kerberos Options for DHCPv6 November 2012 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 isShow full document text
