Abstract
This document defines a new password authenticated key exchange based pre-authentication mechanism for performing Kerberos authentication. This mechanism has three goals. First, it makes Kerberos pre- authentication more resilient against time synchronization errors by removing the need to transfer an encrypted timestamp. Second, it increases the security of the Kerberos pre-authentication exchange by making offline brute-force attacks impossible. Third, it enables the use of secure second factor authentication without FAST by utilizing the existing trust relationship established by the shared first factor.
