1 Kerberos Version 5, Release 1.3.2
6 Unpacking the Source Distribution
7 ---------------------------------
9 The source distribution of Kerberos 5 comes in a gzipped tarfile,
10 krb5-1.3.2.tar.gz. Instructions on how to extract the entire
13 If you have the GNU tar program and gzip installed, you can simply do:
15 gtar zxpf krb5-1.3.2.tar.gz
17 If you don't have GNU tar, you will need to get the FSF gzip
18 distribution and use gzcat:
20 gzcat krb5-1.3.2.tar.gz | tar xpf -
22 Both of these methods will extract the sources into krb5-1.3.2/src and
23 the documentation into krb5-1.3.2/doc.
25 Building and Installing Kerberos 5
26 ----------------------------------
28 The first file you should look at is doc/install-guide.ps; it contains
29 the notes for building and installing Kerberos 5. The info file
30 krb5-install.info has the same information in info file format. You
31 can view this using the GNU emacs info-mode, or by using the
32 standalone info file viewer from the Free Software Foundation. This
33 is also available as an HTML file, install.html.
35 Other good files to look at are admin-guide.ps and user-guide.ps,
36 which contain the system administrator's guide, and the user's guide,
37 respectively. They are also available as info files
38 kerberos-admin.info and krb5-user.info, respectively. These files are
39 also available as HTML files.
41 If you are attempting to build under Windows, please see the
42 src/windows/README file.
47 Please report any problems/bugs/comments using the krb5-send-pr
48 program. The krb5-send-pr program will be installed in the sbin
49 directory once you have successfully compiled and installed Kerberos
50 V5 (or if you have installed one of our binary distributions).
52 If you are not able to use krb5-send-pr because you haven't been able
53 compile and install Kerberos V5 on any platform, you may send mail to
56 You may view bug reports by visiting
58 http://krbdev.mit.edu/rt/

138 * [1790] The Linux build uses $(CC) to create shared libraries,
139 avoiding a libgcc problem when building libdb.
141 * [1792] The lib/kadm5 unit tests now work around a Solaris 9
144 * [1793] The test suite works around some Tru64 and Irix RPATH

148 * [1799] kadmind supports callouts to the Apple password server.
150 * [1893] KRB-SAFE messages from older releases can now be read

152 KRB-SAFE message, and experienced problems when re-encoding. Found
155 * [1962] MS LSA tickets with short remaining lifetimes will be
156 rejected in favor of retrieving tickets bypassing the LSA cache.
158 * [1973] sendto_kdc.c now closes sockets with closesocket() instead of
159 close(), avoiding a descriptor leak on Windows.
161 * [1979] An erroneously short initial sequence number mask has been
164 * [2028] KfW now displays a kinit dialog when GSS fails to find

183 * [2104] On Windows, only define strcasecmp and strncasecmp
184 replacement macros if said functions are missing.
186 * [2106] Return an error for unimplemented ccache functions, rather
187 than calling through a null pointer.
189 * [2118] Applied patch from Will Fiveash to use correct parameter for
190 KDC TCP listening sockets.
192 * [2144,2230] Memory management errors in the Windows gss.exe test

232 Reported by David Thompson.
234 Notes, Major Changes, and Known Bugs for 1.3.1
235 ----------------------------------------------
237 * [1681] The incorrect encoding of the ETYPE-INFO2 preauthentication
238 hint is no longer emitted, and the both the incorrect and the
239 correct encodings of ETYPE-INFO2 are now accepted. We STRONGLY
240 encourage deploying krb5-1.3.1 in preference to 1.3, especially on
241 client installations, as the 1.3 release did not conform to the
242 internet-draft for the revised Kerberos protocol in its encoding of
245 * [1683] The non-caching getaddrinfo() API on Mac OS X, which was
246 causing significant slowdowns under some circumstances, has been
249 Minor changes in 1.3.1
250 ----------------------
252 * [1015] gss_accept_sec_context() now passes correct arguments to
253 TREAD_STR() when reading options beyond the forwarded credential
254 option. Thanks to Emily Ratliff.
256 * [1365] The GSSAPI initiator credentials are no longer cached inside
259 * [1651] A buffer overflow in krb_get_admhst() has been fixed.
261 * [1655] krb5_get_permitted_enctypes() and krb5_set_real_time() are
262 now exported for use by Samba.
264 * [1656] gss_init_sec_context() no longer leaks credentials under some
267 * [1657] krb_get_lrealm() no longer returns "ATHENA.MIT.EDU"
270 * [1664] The crypto library no longer has bogus dependencies on
273 * [1665] krb5_init_context() no longer multiply registers error tables
274 when called more than once, preventing a memory leak.
276 * [1666] The GSS_C_NT_* symbols are now exported from gssapi32.dll on
279 * [1667] ms2mit now imports any tickets with supported enctypes, and
280 does not import invalid tickets.
282 * [1677] krb5_gss_register_acceptor_identity() no longer has an
283 off-by-one in its memory allocation.
285 * [1679] krb5_principal2salt is now exported on all platforms.
287 * [1684] The file credentials cache is now supported if USE_CCAPI is
288 defined, i.e., for KfM and KfW.
290 * [1691] Documentation for the obsolete kdc_supported_enctypes config
291 variable has been removed.
293 Notes, Major Changes, and Known Bugs for 1.3
294 --------------------------------------------
296 * We now install the compile_et program, so other packages can use the
297 installed com_err library with their own error tables. (If you use
298 our com_err code, that is; see below.)
300 * The header files we install now assume ANSI/ISO C ('89, not '99).
301 We have stopped testing on SunOS 4, even with gcc. Some of our code
302 now has C89-based assumptions, like free(NULL) being well defined,
303 that will probably frustrate any attempts to run this code under SunOS
304 4 or other pre-C89 systems.
306 * Some new code, bug fixes, and cleanup for IPv6 support. Most of the
307 code should support IPv6 transparently now. The RPC code (and
308 therefore the admin system, which is based on it) does not yet
309 support IPv6. The support for Kerberos 4 may work with IPv6 in very
310 limited ways, if the address checking is turned off. The FTP client
311 and server do not have support for the new protocol messages needed
312 for IPv6 support (RFC 2428).
314 * We have upgraded to autoconf 2.52 (or later), and the syntax for
315 specifying certain configuration options have changed. For example,
316 autoconf 2.52 configure scripts let you specify command-line options
317 like "configure CC=/some/path/foo-cc", so we have removed some of
318 our old options like --with-cc in favor of this approach.
320 * The client libraries can now use TCP to connect to the KDC. This
321 may be necessary when talking to Microsoft KDCs (domain controllers),
322 if they issue you tickets with lots of PAC data.
324 * If you have versions of the com_err or ss installed locally, you can
325 use the --with-system-et and --with-system-ss configure options to
326 use them rather than using the versions supplied here. Note that
327 the interfaces are assumed to be similar to those we supply; in
328 particular, some older, divergent versions of the com_err library
329 may not work with the krb5 sources. Many configure-time variables
330 can be used to help the compiler and linker find the installed
331 packages; see the build documentation for details.
333 * The AES cryptosystem has been implemented. However, support in the
334 Kerberos GSSAPI mechanism has not been written (or even fully
335 specified), so it's not fully enabled. See the documentation for
338 Major changes listed by ticket ID
339 ---------------------------------
341 * [492] PRNG breakage on 64-bit platforms no longer an issue due to
342 new PRNG implementation.
344 * [523] Client library is now compatible with the RC4-based
345 cryptosystem used by Windows 2000.
347 * [709] krb4 long lifetime support has been implemented.
349 * [880] krb5_gss_register_acceptor_identity() implemented (is called
350 gsskrb5_register_acceptor_identity() by Heimdal).
352 * [1087] ftpd no longer requires channel bindings, allowing easier use
353 of ftp from behind a NAT.
355 * [1156, 1209] It is now possible to use the system com_err to build
358 * [1174] TCP support added to client library.
360 * [1175] TCP support added to the KDC, but is disabled by default.
362 * [1176] autoconf-2.5x is now required by the build system.
364 * [1184] It is now possible to use the system Berkeley/Sleepycat DB
365 library to build this release.
367 * [1189, 1251] The KfM krb4 library source base has been merged.
369 * [1190] The default KDC master key type is now triple-DES. KDCs
370 being updated may need their config files updated if they are not
371 already specifying the master key type.
373 * [1190] The default ticket lifetime and default maximum renewable
374 ticket lifetime have been extended to one day and one week,
377 * [1191] A new script, k5srvutil, may be used to manipulate keytabs in
378 ways similar to the krb4 ksrvutil utility.
380 * [1281] The "fakeka" program, which emulates the AFS kaserver, has
381 been integrated. Thanks to Ken Hornstein.
383 * [1343] The KDC now defaults to not answering krb4 requests.
385 * [1344] Addressless tickets are requested by default now.
387 * [1372] There is no longer a need to create a special keytab for
388 kadmind. The legacy administration daemons "kadmind4" and
389 "v5passwdd" will still require a keytab, though.
391 * [1377, 1442, 1443] The Microsoft set-password protocol has been
392 implemented. Thanks to Paul Nelson.
394 * [1385, 1395, 1410] The krb4 protocol vulnerabilities
395 [MITKRB5-SA-2003-004] have been worked around. Note that this will
396 disable krb4 cross-realm functionality, as well as krb4 triple-DES
397 functionality. Please see doc/krb4-xrealm.txt for details of the
400 * [1393] The xdrmem integer overflows [MITKRB5-SA-2003-003] have
403 * [1397] The krb5_principal buffer bounds problems
404 [MITKRB5-SA-2003-005] have been fixed. Thanks to Nalin Dahyabhai.
406 * [1415] Subsession key negotiation has been fixed to allow for
407 server-selected subsession keys in the future.
409 * [1418, 1429, 1446, 1484, 1486, 1487, 1535, 1621] The AES
410 cryptosystem has been implemented. It is not usable for GSSAPI,
413 * [1491] The client-side functionality of the krb524 library has been
414 moved into the krb5 library.
416 * [1550] SRV record support exists for Kerberos v4.
418 * [1551] The heuristic for locating the Kerberos v4 KDC by prepending
419 "kerberos." to the realm name if no config file or DNS information
420 is available has been removed.
422 * [1568, 1067] A krb524 stub library is built on Windows.

516 * [999] The kdc_default_options configuration variable is now honored.
517 Thanks to Emily Ratliff.
519 * [1006] Client library, as well as KDC, now perform reasonable
520 sorting of ETYPE-INFO preauthentication data.
522 * [1055] NULL pointer dereferences in code calling
523 krb5_change_password() have been fixed.
525 * [1063] Initial credentials acquisition failures related to client
526 host having a large number of local network interfaces should be
529 * [1064] Incorrect option parsing in the gssapi library is no longer
530 relevant due to removal of the "v2" mechanism.

544 * [1136] Some documentation for the setup of cross-realm
545 authentication has been added.
547 * [1164] krb5_auth_con_gen_addrs() now properly returns errno instead
