                  Kerberos Version 5, Release 1.3.2

                            Release Notes
                        The MIT Kerberos Team

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

The source distribution of Kerberos 5 comes in a gzipped tarfile,
krb5-1.3.2.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 krb5-1.3.2.tar.gz

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

        gzcat krb5-1.3.2.tar.gz | tar xpf -

Both of these methods will extract the sources into krb5-1.3.2/src and
the documentation into krb5-1.3.2/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.

Notes, Major Changes, and Known Bugs for 1.3.2
----------------------------------------------

* [2040, 1471, 2067] Support for AES in GSSAPI has been implemented.
  This corresponds to the in-progress work in the IETF (CFX).

Minor changes in 1.3.2
----------------------

* [1437] Applied patch from Stephen Grau so kinit returns non-zero
  status under certain failure conditions where it had previously
  returned zero.

* [1586] On Windows, the krb4 CREDENTIALS structure has been changed
  to align with KfW's version of the structure.

* [1613] Applied patch from Dave Shrimpton to avoid truncation of
  dates output from the kadmin CLI when long time zone names are
  used.

* [1622] krshd no longer calls syslog from inside a signal handler, in
  an effort to avoid deadlocks on exit.

* [1649] A com_err test program compiles properly on Darwin now.

* [1692] A new configuration file tag "master_kdc" has been added to
  allow master KDCs to be designated separately from admin servers.

* [1702] krb5_get_host_realm() and krb5_free_host_realm() are no
  longer marked as KRB5_PRIVATE.

* [1711] Applied patch from Harry McGavran Jr to allow fake-addrinfo.h
  to compile on libc5 Linux platforms.

* [1712] Applied patch from Cesar Garcia to fix lifetime computation
  in krb524 ticket conversion.

* [1713] Fixed an endianness bug in krb524d, found by Cesar Garcia.

* [1715] kadmind4 and v5passwdd are no longer installed on Mac OS X.

* [1718] The krb4 library configure script now recognizes
  OpenDarwin/x86.  Bug found by Rob Braun.

* [1721] krb5_get_init_creds_password() no longer returns a spurious
  KRB5_REALM_UNKNOWN if DNS SRV record support is turned off.

* [1730] krb_mk_auth() no longer overzealously clears the key
  schedule.

* [1731] A double-free related to reading forwarded credentials has
  been fixed.  Found by Joseph Galbraith.

* [1770] Applied patch from Maurice Massar to fix a foreachaddr()
  problem that was causing the KDC to segfault on startup.

* [1790] The Linux build uses $(CC) to create shared libraries,
  avoiding a libgcc problem when building libdb.

* [1792] The lib/kadm5 unit tests now work around a Solaris 9
  pty-close bug.

* [1799] kadmind supports callouts to the Apple password server.

* [1893] KRB-SAFE messages from older releases can now be read
  successfully.  Prior 1.3.x releases did not save the encoded
  KRB-SAFE message, and experienced problems when re-encoding.  Found
  by Scooter Morris.

* [1962] MS LSA tickets with short remaining lifetimes will be
  rejected in favor of retrieving tickets bypassing the LSA cache.

* [1973] sendto_kdc.c now closes sockets with closesocket() instead of
  close(), avoiding a descriptor leak on Windows.

* [1979] An erroneously short initial sequence number mask has been
  fixed.

* [2028] KfW now displays a kinit dialog when GSS fails to find
  tickets.

* [2049] Added a new ccache type "MSLSA:" for read-only access to the
  MS Windows LSA cache.

* [2060] GSSAPI's idea of the default ccache is less sticky now.

* [2068] The profile library includes prof-int.h before conditionals
  that rely on it.

Notes, Major Changes, and Known Bugs for 1.3.1
----------------------------------------------

* [1681] The incorrect encoding of the ETYPE-INFO2 preauthentication
  hint is no longer emitted, and the both the incorrect and the
  correct encodings of ETYPE-INFO2 are now accepted.  We STRONGLY
  encourage deploying krb5-1.3.1 in preference to 1.3, especially on
  client installations, as the 1.3 release did not conform to the
  internet-draft for the revised Kerberos protocol in its encoding of
  ETYPE-INFO2.

* [1683] The non-caching getaddrinfo() API on Mac OS X, which was
  causing significant slowdowns under some circumstances, has been
  worked around.

Minor changes in 1.3.1
----------------------

* [1015] gss_accept_sec_context() now passes correct arguments to
  TREAD_STR() when reading options beyond the forwarded credential
  option.  Thanks to Emily Ratliff.

* [1365] The GSSAPI initiator credentials are no longer cached inside
  the GSSAPI library.

* [1651] A buffer overflow in krb_get_admhst() has been fixed.

* [1655] krb5_get_permitted_enctypes() and krb5_set_real_time() are
  now exported for use by Samba.

* [1656] gss_init_sec_context() no longer leaks credentials under some
  error conditions.

* [1657] krb_get_lrealm() no longer returns "ATHENA.MIT.EDU"
  inappropriately.

* [1664] The crypto library no longer has bogus dependencies on
  com_err.

* [1665] krb5_init_context() no longer multiply registers error tables
  when called more than once, preventing a memory leak.

* [1666] The GSS_C_NT_* symbols are now exported from gssapi32.dll on
  Windows.

* [1667] ms2mit now imports any tickets with supported enctypes, and
  does not import invalid tickets.

* [1677] krb5_gss_register_acceptor_identity() no longer has an
  off-by-one in its memory allocation.

* [1679] krb5_principal2salt is now exported on all platforms.

* [1684] The file credentials cache is now supported if USE_CCAPI is
  defined, i.e., for KfM and KfW.

* [1691] Documentation for the obsolete kdc_supported_enctypes config
  variable has been removed.

Notes, Major Changes, and Known Bugs for 1.3
--------------------------------------------

* We now install the compile_et program, so other packages can use the
  installed com_err library with their own error tables.  (If you use
  our com_err code, that is; see below.)

* The header files we install now assume ANSI/ISO C ('89, not '99).
  We have stopped testing on SunOS 4, even with gcc.  Some of our code
  now has C89-based assumptions, like free(NULL) being well defined,
  that will probably frustrate any attempts to run this code under SunOS
  4 or other pre-C89 systems.

* Some new code, bug fixes, and cleanup for IPv6 support.  Most of the
  code should support IPv6 transparently now.  The RPC code (and
  therefore the admin system, which is based on it) does not yet
  support IPv6.  The support for Kerberos 4 may work with IPv6 in very
  limited ways, if the address checking is turned off.  The FTP client
  and server do not have support for the new protocol messages needed
  for IPv6 support (RFC 2428).

* We have upgraded to autoconf 2.52 (or later), and the syntax for
  specifying certain configuration options have changed.  For example,
  autoconf 2.52 configure scripts let you specify command-line options
  like "configure CC=/some/path/foo-cc", so we have removed some of
  our old options like --with-cc in favor of this approach.

* The client libraries can now use TCP to connect to the KDC.  This
  may be necessary when talking to Microsoft KDCs (domain controllers),
  if they issue you tickets with lots of PAC data.

* If you have versions of the com_err or ss installed locally, you can
  use the --with-system-et and --with-system-ss configure options to
  use them rather than using the versions supplied here.  Note that
  the interfaces are assumed to be similar to those we supply; in
  particular, some older, divergent versions of the com_err library
  may not work with the krb5 sources.  Many configure-time variables
  can be used to help the compiler and linker find the installed
  packages; see the build documentation for details.

* The AES cryptosystem has been implemented.  However, support in the
  Kerberos GSSAPI mechanism has not been written (or even fully
  specified), so it's not fully enabled.  See the documentation for
  details.

Major changes listed by ticket ID
---------------------------------

* [492] PRNG breakage on 64-bit platforms no longer an issue due to
  new PRNG implementation.

* [523] Client library is now compatible with the RC4-based
  cryptosystem used by Windows 2000.

* [709] krb4 long lifetime support has been implemented.

* [880] krb5_gss_register_acceptor_identity() implemented (is called
  gsskrb5_register_acceptor_identity() by Heimdal).

* [1087] ftpd no longer requires channel bindings, allowing easier use
  of ftp from behind a NAT.

* [1156, 1209] It is now possible to use the system com_err to build
  this release.

* [1174] TCP support added to client library.

* [1175] TCP support added to the KDC, but is disabled by default.

* [1176] autoconf-2.5x is now required by the build system.

* [1184] It is now possible to use the system Berkeley/Sleepycat DB
  library to build this release.

* [1189, 1251] The KfM krb4 library source base has been merged.

* [1190] The default KDC master key type is now triple-DES.  KDCs
  being updated may need their config files updated if they are not
  already specifying the master key type.

* [1190] The default ticket lifetime and default maximum renewable
  ticket lifetime have been extended to one day and one week,
  respectively.

* [1191] A new script, k5srvutil, may be used to manipulate keytabs in
  ways similar to the krb4 ksrvutil utility.

* [1281] The "fakeka" program, which emulates the AFS kaserver, has
  been integrated.  Thanks to Ken Hornstein.

* [1343] The KDC now defaults to not answering krb4 requests.

* [1344] Addressless tickets are requested by default now.

* [1372] There is no longer a need to create a special keytab for
  kadmind.  The legacy administration daemons "kadmind4" and
  "v5passwdd" will still require a keytab, though.

* [1377, 1442, 1443] The Microsoft set-password protocol has been
  implemented.  Thanks to Paul Nelson.

* [1385, 1395, 1410] The krb4 protocol vulnerabilities
  [MITKRB5-SA-2003-004] have been worked around.  Note that this will
  disable krb4 cross-realm functionality, as well as krb4 triple-DES
  functionality.  Please see doc/krb4-xrealm.txt for details of the
  patch.

* [1393] The xdrmem integer overflows [MITKRB5-SA-2003-003] have
  been fixed.

* [1397] The krb5_principal buffer bounds problems
  [MITKRB5-SA-2003-005] have been fixed.  Thanks to Nalin Dahyabhai.

* [1415] Subsession key negotiation has been fixed to allow for
  server-selected subsession keys in the future.

* [1418, 1429, 1446, 1484, 1486, 1487, 1535, 1621] The AES
  cryptosystem has been implemented.  It is not usable for GSSAPI,
  though.

* [1491] The client-side functionality of the krb524 library has been
  moved into the krb5 library.

* [1550] SRV record support exists for Kerberos v4.

* [1551] The heuristic for locating the Kerberos v4 KDC by prepending
  "kerberos." to the realm name if no config file or DNS information
  is available has been removed.

* [1568, 1067] A krb524 stub library is built on Windows.

* [986] Related to [677], problems with the ordering of LDFLAGS
  initialization rendered irrelevant by use of native autoconf
  idioms.

  encoded as zero-length strings.

* [1226] Client-side support for SAM hardware-based preauth
  implemented.

* [1229] The keytab search logic no longer fails prematurely if an
  incorrect encryption type is found.  Thanks to Wyllys Ingersoll.

* [1232] If the master KDC cannot be resolved, but a slave is
  reachable, the client library now returns the real error from the
  slave rather than the resolution failure from the master.  Thanks to
  Ben Cox.

* [1587] A more standard autoconf test to locate the C compiler allows
  for gcc to be found by default without additional configuration
  arguments.

* [1593] Replay cache filenames are now escaped with hyphens, not
  backslashes.

* [1598] MacOS 9 support removed from in-tree com_err.
