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.
