1 Kerberos Version 5, Release 1.3.3
6 Unpacking the Source Distribution
7 ---------------------------------
9 The source distribution of Kerberos 5 comes in a gzipped tarfile,
10 krb5-1.3.3.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 krb5-1.3.3.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 krb5-1.3.3.tar.gz | tar xpf -
22 Both of these methods will extract the sources into krb5-1.3.3/src and
23 the documentation into krb5-1.3.3/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

161 * [1790] The Linux build uses $(CC) to create shared libraries,
162 avoiding a libgcc problem when building libdb.
164 * [1792] The lib/kadm5 unit tests now work around a Solaris 9
167 * [1793] The test suite works around some Tru64 and Irix RPATH

171 * [1799] kadmind supports callouts to the Apple password server.
173 * [1893] KRB-SAFE messages from older releases can now be read

178 * [1962] MS LSA tickets with short remaining lifetimes will be
179 rejected in favor of retrieving tickets bypassing the LSA cache.
181 * [1973] sendto_kdc.c now closes sockets with closesocket() instead of
182 close(), avoiding a descriptor leak on Windows.
184 * [1979] An erroneously short initial sequence number mask has been
187 * [2028] KfW now displays a kinit dialog when GSS fails to find
190 * [2051] Missing exports have been added to krb4_32.def on Windows.

206 * [2104] On Windows, only define strcasecmp and strncasecmp
207 replacement macros if said functions are missing.
209 * [2106] Return an error for unimplemented ccache functions, rather
210 than calling through a null pointer.
212 * [2118] Applied patch from Will Fiveash to use correct parameter for
213 KDC TCP listening sockets.
215 * [2144,2230] Memory management errors in the Windows gss.exe test

249 * [2195, 2236, 2241, 2245] The Solaris 9 pty-close bug, which was
250 affecting the test suite, has been worked around by hacking
251 scheduler priorities. See the installation notes for details.

255 Reported by David Thompson.
257 Notes, Major Changes, and Known Bugs for 1.3.1
258 ----------------------------------------------
260 * [1681] The incorrect encoding of the ETYPE-INFO2 preauthentication
261 hint is no longer emitted, and the both the incorrect and the
262 correct encodings of ETYPE-INFO2 are now accepted. We STRONGLY
263 encourage deploying krb5-1.3.1 in preference to 1.3, especially on
264 client installations, as the 1.3 release did not conform to the
265 internet-draft for the revised Kerberos protocol in its encoding of
268 * [1683] The non-caching getaddrinfo() API on Mac OS X, which was
269 causing significant slowdowns under some circumstances, has been
272 Minor changes in 1.3.1
273 ----------------------
275 * [1015] gss_accept_sec_context() now passes correct arguments to
276 TREAD_STR() when reading options beyond the forwarded credential
277 option. Thanks to Emily Ratliff.
279 * [1365] The GSSAPI initiator credentials are no longer cached inside
282 * [1651] A buffer overflow in krb_get_admhst() has been fixed.
284 * [1655] krb5_get_permitted_enctypes() and krb5_set_real_time() are
285 now exported for use by Samba.
287 * [1656] gss_init_sec_context() no longer leaks credentials under some
290 * [1657] krb_get_lrealm() no longer returns "ATHENA.MIT.EDU"
293 * [1664] The crypto library no longer has bogus dependencies on
296 * [1665] krb5_init_context() no longer multiply registers error tables
297 when called more than once, preventing a memory leak.
299 * [1666] The GSS_C_NT_* symbols are now exported from gssapi32.dll on
302 * [1667] ms2mit now imports any tickets with supported enctypes, and
303 does not import invalid tickets.
305 * [1677] krb5_gss_register_acceptor_identity() no longer has an
306 off-by-one in its memory allocation.
308 * [1679] krb5_principal2salt is now exported on all platforms.
310 * [1684] The file credentials cache is now supported if USE_CCAPI is
311 defined, i.e., for KfM and KfW.
313 * [1691] Documentation for the obsolete kdc_supported_enctypes config
314 variable has been removed.
316 Notes, Major Changes, and Known Bugs for 1.3
317 --------------------------------------------
319 * We now install the compile_et program, so other packages can use the
320 installed com_err library with their own error tables. (If you use
321 our com_err code, that is; see below.)
323 * The header files we install now assume ANSI/ISO C ('89, not '99).
324 We have stopped testing on SunOS 4, even with gcc. Some of our code
325 now has C89-based assumptions, like free(NULL) being well defined,
326 that will probably frustrate any attempts to run this code under SunOS
327 4 or other pre-C89 systems.
329 * Some new code, bug fixes, and cleanup for IPv6 support. Most of the
330 code should support IPv6 transparently now. The RPC code (and
331 therefore the admin system, which is based on it) does not yet
332 support IPv6. The support for Kerberos 4 may work with IPv6 in very
333 limited ways, if the address checking is turned off. The FTP client
334 and server do not have support for the new protocol messages needed
335 for IPv6 support (RFC 2428).
337 * We have upgraded to autoconf 2.52 (or later), and the syntax for
338 specifying certain configuration options have changed. For example,
339 autoconf 2.52 configure scripts let you specify command-line options
340 like "configure CC=/some/path/foo-cc", so we have removed some of
341 our old options like --with-cc in favor of this approach.
343 * The client libraries can now use TCP to connect to the KDC. This
344 may be necessary when talking to Microsoft KDCs (domain controllers),
345 if they issue you tickets with lots of PAC data.
347 * If you have versions of the com_err or ss installed locally, you can
348 use the --with-system-et and --with-system-ss configure options to
349 use them rather than using the versions supplied here. Note that
350 the interfaces are assumed to be similar to those we supply; in
351 particular, some older, divergent versions of the com_err library
352 may not work with the krb5 sources. Many configure-time variables
353 can be used to help the compiler and linker find the installed
354 packages; see the build documentation for details.
356 * The AES cryptosystem has been implemented. However, support in the
357 Kerberos GSSAPI mechanism has not been written (or even fully
358 specified), so it's not fully enabled. See the documentation for
361 Major changes listed by ticket ID
362 ---------------------------------
364 * [492] PRNG breakage on 64-bit platforms no longer an issue due to
365 new PRNG implementation.
367 * [523] Client library is now compatible with the RC4-based
368 cryptosystem used by Windows 2000.
370 * [709] krb4 long lifetime support has been implemented.
372 * [880] krb5_gss_register_acceptor_identity() implemented (is called
373 gsskrb5_register_acceptor_identity() by Heimdal).
375 * [1087] ftpd no longer requires channel bindings, allowing easier use
376 of ftp from behind a NAT.
378 * [1156, 1209] It is now possible to use the system com_err to build
381 * [1174] TCP support added to client library.
383 * [1175] TCP support added to the KDC, but is disabled by default.
385 * [1176] autoconf-2.5x is now required by the build system.
387 * [1184] It is now possible to use the system Berkeley/Sleepycat DB
388 library to build this release.
390 * [1189, 1251] The KfM krb4 library source base has been merged.
392 * [1190] The default KDC master key type is now triple-DES. KDCs
393 being updated may need their config files updated if they are not
394 already specifying the master key type.
396 * [1190] The default ticket lifetime and default maximum renewable
397 ticket lifetime have been extended to one day and one week,
400 * [1191] A new script, k5srvutil, may be used to manipulate keytabs in
401 ways similar to the krb4 ksrvutil utility.
403 * [1281] The "fakeka" program, which emulates the AFS kaserver, has
404 been integrated. Thanks to Ken Hornstein.
406 * [1343] The KDC now defaults to not answering krb4 requests.
408 * [1344] Addressless tickets are requested by default now.
410 * [1372] There is no longer a need to create a special keytab for
411 kadmind. The legacy administration daemons "kadmind4" and
412 "v5passwdd" will still require a keytab, though.
414 * [1377, 1442, 1443] The Microsoft set-password protocol has been
415 implemented. Thanks to Paul Nelson.
417 * [1385, 1395, 1410] The krb4 protocol vulnerabilities
418 [MITKRB5-SA-2003-004] have been worked around. Note that this will
419 disable krb4 cross-realm functionality, as well as krb4 triple-DES
420 functionality. Please see doc/krb4-xrealm.txt for details of the
423 * [1393] The xdrmem integer overflows [MITKRB5-SA-2003-003] have
426 * [1397] The krb5_principal buffer bounds problems
427 [MITKRB5-SA-2003-005] have been fixed. Thanks to Nalin Dahyabhai.
429 * [1415] Subsession key negotiation has been fixed to allow for
430 server-selected subsession keys in the future.
432 * [1418, 1429, 1446, 1484, 1486, 1487, 1535, 1621] The AES
433 cryptosystem has been implemented. It is not usable for GSSAPI,
436 * [1491] The client-side functionality of the krb524 library has been
437 moved into the krb5 library.
439 * [1550] SRV record support exists for Kerberos v4.
441 * [1551] The heuristic for locating the Kerberos v4 KDC by prepending
442 "kerberos." to the realm name if no config file or DNS information
443 is available has been removed.
445 * [1568, 1067] A krb524 stub library is built on Windows.

465 aligned with the original krb4 and CNS APIs.
467 * [608] login.krb5 handles SIGHUP more sanely now and thus avoids
468 getting the session into a weird state w.r.t. job control.
470 * [620] krb4 encrypted rcp should work a little better now. Thanks to
473 * [647] libtelnet/kerberos5.c no longer uses internal include files.
475 * [673] Weird echoing of admin password in kadmin client worked around
476 by not using buffered stdio calls to read passwords.
478 * [677] The build system has been reworked to allow the user to set
479 CFLAGS, LDFLAGS, CPPFLAGS, etc. reasonably.
481 * [680] Related to [673], rewrite krb5_prompter_posix() to no longer
482 use longjmp(), thus avoiding some bugs relating to non-restoration
483 of terminal settings.
485 * [697] login.krb5 no longer zeroes out the terminal window size.
487 * [710] decomp_ticket() in libkrb4 now looks up the local realm name

519 * [953] des3 no longer failing on Windows due to SHA1 implementation
522 * [964] kdb_init_hist() no longer fails if master_key_enctype is not
523 in supported_enctypes.
525 * [970] A minor inconsistency in ccache.tex has been fixed.
527 * [971] option parsing bugs rendered irrelevant by removal of unused

537 AC_PROG_CC is used instead now.
539 * [999] The kdc_default_options configuration variable is now honored.
540 Thanks to Emily Ratliff.
542 * [1006] Client library, as well as KDC, now perform reasonable
543 sorting of ETYPE-INFO preauthentication data.
545 * [1055] NULL pointer dereferences in code calling
546 krb5_change_password() have been fixed.
548 * [1063] Initial credentials acquisition failures related to client
549 host having a large number of local network interfaces should be
552 * [1064] Incorrect option parsing in the gssapi library is no longer
553 relevant due to removal of the "v2" mechanism.

563 * [1102] gssapi_generic.h should now work with C++.
565 * [1135] The kadm5 ACL system is better documented.
567 * [1136] Some documentation for the setup of cross-realm
568 authentication has been added.
570 * [1164] krb5_auth_con_gen_addrs() now properly returns errno instead
571 of -1 if getpeername() fails.
573 * [1173] Address-less forwardable tickets will remain address-less

611 incorrect encryption type is found. Thanks to Wyllys Ingersoll.
613 * [1232] If the master KDC cannot be resolved, but a slave is
614 reachable, the client library now returns the real error from the
