Abstract:
   This document defines a new pre-authentication mechanism for the
   Kerberos protocol that uses a password authenticated key exchange.
   This document has three goals.  First, increase the security of
   Kerberos pre-authentication exchanges by making offline brute-force
   attacks infeasible.  Second, enable the use of second factor
   authentication without relying on FAST.  This is achieved using the
   existing trust relationship established by the shared first factor.
   Third, make Kerberos pre-authentication more resilient against time
   synchronization errors by removing the need to transfer an encrypted
   timestamp from the client.
