The MIT Kerberos Team announces the availability of MIT Kerberos 5
Release 1.13.  Please see below for a list of some major changes
included, or consult the README file in the source tree for a more
detailed list of significant changes.

DES transition
==============

The Data Encryption Standard (DES) is widely recognized as weak.  The
krb5-1.7 release contains measures to encourage sites to migrate away
- From using single-DES cryptosystems.  Among these is a configuration
variable that enables "weak" enctypes, which defaults to "false"
beginning with krb5-1.8.

Major changes in 1.13 (2014-10-15)
==================================

Administrator experience:

* Add support for accessing KDCs via an HTTPS proxy server using the
  MS-KKDCP protocol.

* Add support for hierarchical incremental propagation, where slaves
  can act as intermediates between an upstream master and other
  downstream slaves.

* Add support for configuring GSS mechanisms using
  /etc/gss/mech.d/*.conf files in addition to /etc/gss/mech.

* Add support to the LDAP KDB module for binding to the LDAP server
  using SASL.

* The KDC listens for TCP connections by default.

* Fix a minor key disclosure vulnerability where using the "keepold"
  option to the kadmin randkey operation could return the old keys.
  [CVE-2014-5351]

User experience:

* Add client support for the Kerberos Cache Manager protocol. If the
  host is running a Heimdal kcm daemon, caches served by the daemon
  can be accessed with the KCM: cache type.

* When built on OS X 10.7 and higher, use "KCM:" as the default cache
  type, unless overridden by command-line options or krb5-config
  values.

Performance:

* Add support for doing unlocked database dumps for the DB2 KDC back
  end, which would allow the KDC and kadmind to continue accessing the
  database during lengthy database dumps.
