Kerberos Version 5, Release 1.3
Release Notes
The MIT Kerberos Team
Unpacking the Source Distribution
---------------------------------
The source distribution of Kerberos 5 comes in a gzipped tarfile,
krb5-1.3.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.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.tar.gz | tar xpf -
Both of these methods will extract the sources into krb5-1.3/src and
the documentation into krb5-1.3/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".
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. [[TODO:
Insert list of (non-)supporting programs and libraries here.]]
* 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, ss, or Berkeley DB packages
installed locally, you can use the --with-system-et,
--with-system-ss, and --with-system-db 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] 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.
Minor changes listed by ticket ID
---------------------------------
* [90] default_principal_flags documented.
* [175] Docs refer to appropriate example domains/IPs now.
* [299] kadmin no longer complains about missing kdc.conf parameters
when it really means krb5.conf parameters.
* [318] Run-time load path for tcl is set now when linking test
programs.
* [443] --includedir honored now.
* [479] unused argument in try_krb4() in login.c deleted.
* [590] The des_read_pw_string() function in libdes425 has been
aligned with the original krb4 and CNS APIs.
* [608] login.krb5 handles SIGHUP more sanely now and thus avoids
getting the session into a weird state w.r.t. job control.
* [620] krb4 encrypted rcp should work a little better now. Thanks to
Greg Hudson.
* [647] libtelnet/kerberos5.c no longer uses internal include files.
* [673] Weird echoing of admin password in kadmin client worked around
by not using buffered stdio calls to read passwords.
* [677] The build system has been reworked to allow the user to set
CFLAGS, LDFLAGS, CPPFLAGS, etc. reasonably.
* [680] Related to [673], rewrite krb5_prompter_posix() to no longer
use longjmp(), thus avoiding some bugs relating to non-restoration
of terminal settings.
* [697] login.krb5 no longer zeroes out the terminal window size.
* [710] decomp_ticket() in libkrb4 now looks up the local realm name
more correctly. Thanks to Booker Bense.
* [771] .rconf files are excluded from the release now.
* [772] LOG_AUTHPRIV syslog facility is now usable for logging on
systems that support it.
* [844] krshd now syslogs using the LOG_AUTH facility.
* [850] Berekely DB build is better integrated into the krb5 library
build process.
* [866] lib/krb5/os/localaddr.c and kdc/network.c use a common source
for local address enumeration now.
* [919] kdc/network.c problems relating to SIOCGIFCONF have been
fixed.
* [922] An overflow in the string-to-time conversion routines has been
fixed.
* [935] des-cbc-md4 now included in default enctypes.
* [939] A minor grammatical error has been fixed in a telnet client
error message.
* [953] des3 no longer failing on Windows due to SHA1 implementation
problems.
* [964] kdb_init_hist() no longer fails if master_key_enctype is not
in supported_enctypes.
* [970] A minor inconsistency in ccache.tex has been fixed.
* [971] option parsing bugs rendered irrelevant by removal of unused
gss mechanism.
* [986] Related to [677], problems with the ordering of LDFLAGS
initialization rendered irrelevant by use of native autoconf
idioms.
* [992] Related to [677], quirks with --with-cc no longer relevant as
AC_PROG_CC is used instead now.
* [999] The kdc_default_options configuration variable is now honored.
Thanks to Emily Ratliff.
* [1006] Client library, as well as KDC, now perform reasonable
sorting of ETYPE-INFO preauthentication data.
* [1055] NULL pointer dereferences in code calling
krb5_change_password() have been fixed.
* [1063] Initial credentials acquisition failures related to client
host having a large number of local network interfaces should be
fixed now.
* [1064] Incorrect option parsing in the gssapi library is no longer
relevant due to removal of the "v2" mechanism.
* [1065, 1225] krb5_get_init_creds_password() should properly warn about
password expiration.
* [1066] printf() argument mismatches in rpc unit tests fixed.

* [1136] Some documentation for the setup of cross-realm
authentication has been added.
* [1164] krb5_auth_con_gen_addrs() now properly returns errno instead
of -1 if getpeername() fails.
* [1173] Address-less forwardable tickets will remain address-less
when forwarded.
* [1178, 1228, 1244, 1246, 1249] Test suite has been stabilized
somewhat.
* [1188] As part of the modernization of our usage of autoconf,
AC_CONFIG_FILES is now used instead of passing a list of files to
AC_OUTPUT.
* [1194] configure will no longer recurse out of the top of the source
tree when attempting to locate the top of the source tree.
* [1192] Documentation for the krb5 afs functionality of krb524d has
been written.
