1 Kerberos Version 5, Release 1.3.1
6 Unpacking the Source Distribution
7 ---------------------------------
9 The source distribution of Kerberos 5 comes in a gzipped tarfile,
10 krb5-1.3.1.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 krb5-1.3.1.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 krb5-1.3.1.tar.gz | tar xpf -
22 Both of these methods will extract the sources into krb5-1.3.1/src and
23 the documentation into krb5-1.3.1/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/

62 Notes, Major Changes, and Known Bugs for 1.3.1
63 ----------------------------------------------
65 * [1681] The incorrect encoding of ETYPE-INFO2 preauthentication hint
66 is no longer emitted, and the both the incorrect and the correct
67 encodings of ETYPE-INFO2 are now accepted. We STRONGLY encourage
68 deploying krb5-1.3.1 in preference to 1.3, especially on client
69 installations, as the 1.3 release did not conform to the
70 internet-draft for the revised Kerberos protocol in its encoding of
73 * [1683] The non-caching getaddrinfo() API on Mac OS X, which was
74 causing significant slowdowns under some circumstances, has been
77 Minor changes in 1.3.1
78 ----------------------
80 * [1015] gss_accept_sec_context() now passes correct arguments to
81 TREAD_STR() when reading options beyond the forwarded credential
82 option. Thanks to Emily Ratliff.
84 * [1365] The GSSAPI initiator credentials are no longer cached inside
87 * [1651] A buffer overflow in krb_get_admhst() has been fixed.
89 * [1655] krb5_get_permitted_enctypes() and krb5_set_real_time() are
90 now exported for use by Samba.
92 * [1656] gss_init_sec_context() no longer leaks credentials under some
95 * [1657] krb_get_lrealm() no longer returns "ATHENA.MIT.EDU"
98 * [1664] The crypto library no longer has bogus dependencies on
101 * [1665] krb5_init_context() no longer multiply registers error tables
102 when called more than once, preventing a memory leak.
104 * [1666] The GSS_C_NT_* symbols are now exported from gssapi32.dll on
107 * [1667] ms2mit now imports any tickets with supported enctypes, and
108 does not import invalid tickets.
110 * [1677] krb5_gss_register_acceptor_identity() no longer has an
111 off-by-one in its memory allocation.
113 * [1679] krb5_principal2salt is now exported on all platforms.
115 * [1684] The file credentials cache is now supported if USE_CCAPI is
116 defined, i.e., for KfM and KfW.
118 Notes, Major Changes, and Known Bugs for 1.3
119 --------------------------------------------
121 * We now install the compile_et program, so other packages can use the
122 installed com_err library with their own error tables. (If you use
123 our com_err code, that is; see below.)
125 * The header files we install now assume ANSI/ISO C ('89, not '99).
126 We have stopped testing on SunOS 4, even with gcc. Some of our code
127 now has C89-based assumptions, like free(NULL) being well defined,
128 that will probably frustrate any attempts to run this code under SunOS
129 4 or other pre-C89 systems.
131 * Some new code, bug fixes, and cleanup for IPv6 support. Most of the
132 code should support IPv6 transparently now. The RPC code (and
133 therefore the admin system, which is based on it) does not yet
134 support IPv6. The support for Kerberos 4 may work with IPv6 in very
135 limited ways, if the address checking is turned off. The FTP client
136 and server do not have support for the new protocol messages needed
137 for IPv6 support (RFC 2428).
139 * We have upgraded to autoconf 2.52 (or later), and the syntax for
140 specifying certain configuration options have changed. For example,
141 autoconf 2.52 configure scripts let you specify command-line options
142 like "configure CC=/some/path/foo-cc", so we have removed some of
143 our old options like --with-cc in favor of this approach.
145 * The client libraries can now use TCP to connect to the KDC. This
146 may be necessary when talking to Microsoft KDCs (domain controllers),
147 if they issue you tickets with lots of PAC data.
149 * If you have versions of the com_err or ss installed locally, you can
150 use the --with-system-et and --with-system-ss configure options to
151 use them rather than using the versions supplied here. Note that
152 the interfaces are assumed to be similar to those we supply; in
153 particular, some older, divergent versions of the com_err library
154 may not work with the krb5 sources. Many configure-time variables
155 can be used to help the compiler and linker find the installed
156 packages; see the build documentation for details.
158 * The AES cryptosystem has been implemented. However, support in the
159 Kerberos GSSAPI mechanism has not been written (or even fully
160 specified), so it's not fully enabled. See the documentation for
163 Major changes listed by ticket ID
164 ---------------------------------
166 * [492] PRNG breakage on 64-bit platforms no longer an issue due to
167 new PRNG implementation.
169 * [523] Client library is now compatible with the RC4-based
170 cryptosystem used by Windows 2000.
172 * [709] krb4 long lifetime support has been implemented.
174 * [880] krb5_gss_register_acceptor_identity() implemented (is called
175 gsskrb5_register_acceptor_identity() by Heimdal).
177 * [1087] ftpd no longer requires channel bindings, allowing easier use
178 of ftp from behind a NAT.
180 * [1156, 1209] It is now possible to use the system com_err to build
183 * [1174] TCP support added to client library.
185 * [1175] TCP support added to the KDC, but is disabled by default.
187 * [1176] autoconf-2.5x is now required by the build system.
189 * [1184] It is now possible to use the system Berkeley/Sleepycat DB
190 library to build this release.
192 * [1189, 1251] The KfM krb4 library source base has been merged.
194 * [1190] The default KDC master key type is now triple-DES. KDCs
195 being updated may need their config files updated if they are not
196 already specifying the master key type.
198 * [1190] The default ticket lifetime and default maximum renewable
199 ticket lifetime have been extended to one day and one week,
202 * [1191] A new script, k5srvutil, may be used to manipulate keytabs in
203 ways similar to the krb4 ksrvutil utility.
205 * [1281] The "fakeka" program, which emulates the AFS kaserver, has
206 been integrated. Thanks to Ken Hornstein.
208 * [1343] The KDC now defaults to not answering krb4 requests.
210 * [1344] Addressless tickets are requested by default now.
212 * [1372] There is no longer a need to create a special keytab for
213 kadmind. The legacy administration daemons "kadmind4" and
214 "v5passwdd" will still require a keytab, though.
216 * [1377, 1442, 1443] The Microsoft set-password protocol has been
217 implemented. Thanks to Paul Nelson.
219 * [1385, 1395, 1410] The krb4 protocol vulnerabilities
220 [MITKRB5-SA-2003-004] have been worked around. Note that this will
221 disable krb4 cross-realm functionality, as well as krb4 triple-DES
222 functionality. Please see doc/krb4-xrealm.txt for details of the
225 * [1393] The xdrmem integer overflows [MITKRB5-SA-2003-003] have
228 * [1397] The krb5_principal buffer bounds problems
229 [MITKRB5-SA-2003-005] have been fixed. Thanks to Nalin Dahyabhai.
231 * [1415] Subsession key negotiation has been fixed to allow for
232 server-selected subsession keys in the future.
234 * [1418, 1429, 1446, 1484, 1486, 1487, 1535, 1621] The AES
235 cryptosystem has been implemented. It is not usable for GSSAPI,
238 * [1491] The client-side functionality of the krb524 library has been
239 moved into the krb5 library.
241 * [1550] SRV record support exists for Kerberos v4.
243 * [1551] The heuristic for locating the Kerberos v4 KDC by prepending
244 "kerberos." to the realm name if no config file or DNS information
245 is available has been removed.
247 * [1568, 1067] A krb524 stub library is built on Windows.

350 * [1063] Initial credentials acquisition failures related to client
351 host having a large number of local network interfaces should be
354 * [1064] Incorrect option parsing in the gssapi library is no longer
355 relevant due to removal of the "v2" mechanism.
