                   Kerberos Version 5, Release 1.7

                            Release Notes
                        The MIT Kerberos Team

Unpacking the Source Distribution
---------------------------------

The source distribution of Kerberos 5 comes in a gzipped tarfile,
krb5-1.7.tar.gz.  Instructions on how to extract the entire
distribution follow.

If you have the GNU tar program and gzip installed, you can simply do:

        gtar zxpf krb5-1.7.tar.gz

If you don't have GNU tar, you will need to get the FSF gzip
distribution and use gzcat:

        gzcat krb5-1.7.tar.gz | tar xpf -

Both of these methods will extract the sources into krb5-1.7/src and
the documentation into krb5-1.7/doc.

Building and Installing Kerberos 5
----------------------------------

The first file you should look at is doc/install-guide.ps; it contains
the notes for building and installing Kerberos 5.  The info file
krb5-install.info has the same information in info file format.  You
can view this using the GNU emacs info-mode, or by using the
standalone info file viewer from the Free Software Foundation.  This
is also available as an HTML file, install.html.

Other good files to look at are admin-guide.ps and user-guide.ps,
which contain the system administrator's guide, and the user's guide,
respectively.  They are also available as info files
kerberos-admin.info and krb5-user.info, respectively.  These files are
also available as HTML files.

If you are attempting to build under Windows, please see the
src/windows/README file.

Reporting Bugs
--------------

Please report any problems/bugs/comments using the krb5-send-pr
program.  The krb5-send-pr program will be installed in the sbin
directory once you have successfully compiled and installed Kerberos
V5 (or if you have installed one of our binary distributions).

If you are not able to use krb5-send-pr because you haven't been able
compile and install Kerberos V5 on any platform, you may send mail to
krb5-bugs@mit.edu.

You may view bug reports by visiting

http://krbdev.mit.edu/rt/

and logging in as "guest" with password "guest".

DES transition
--------------

The Data Encryption Standard (DES) is widely recognized as weak.  The
krb5-1.7 release will contain measures to encourage sites to migrate
away from using single-DES cryptosystems.  Among these is a
configuration variable that enables "weak" enctypes, but will default
to "false" in the future.  Depending on the outcome of ongoing
discussion on krbdev@mit.edu, this default could change prior to the
final release of krb5-1.7.

Additional measures to ease the transition away from DES are planned
for the final krb5-1.7 release.

Major changes in 1.7
--------------------

* Remove support for version 4 of the Kerberos protocol (krb4).

* New libdefaults configuration variable "allow_weak_crypto".  NOTE:
  Currently defaults to "false", but may default to "true" in a future
  release.  Setting this variable to "false" will have the effect of
  removing weak enctypes (currently defined to be all single-DES
  enctypes) from permitted_enctypes, default_tkt_enctypes, and
  default_tgs_enctypes.

* Client library now follows client principal referrals, for
  compatibility with Windows.

* KDC can issue realm referrals for service principals based on domain
  names.

* Encryption algorithm negotiation (RFC 4537).

* In the replay cache, use a hash over the complete ciphertext to
  avoid false-positive replay indications.

* Microsoft GSS_WrapEX, implemented using the gss_iov API, which is
  similar to the equivalent SSPI functionality.

* DCE RPC, including three-leg GSS context setup and unencapsulated
  GSS tokens.

* NTLM recognition support in GSS-API, to facilitate dropping in an
  NTLM implementation.

* KDC support for principal aliases, if the back end supports them.

* Microsoft set/change password (RFC 3244) protocol in kadmind.

* Master key rollover support.
