1 Kerberos Version 5, Release 1.3
6 Unpacking the Source Distribution
7 ---------------------------------
9 The source distribution of Kerberos 5 comes in a gzipped tarfile,
10 krb5-1.3.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.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.tar.gz | tar xpf -
22 Both of these methods will extract the sources into krb5-1.3/src and
23 the documentation into krb5-1.3/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
58 http://krbdev.mit.edu/rt/
60 and logging in as "guest" with password "guest".
62 Notes, Major Changes, and Known Bugs for 1.3
63 --------------------------------------------
65 * We now install the compile_et program, so other packages can use the
66 installed com_err library with their own error tables. (If you use
67 our com_err code, that is; see below.)
69 * The header files we install now assume ANSI/ISO C ('89, not '99).
70 We have stopped testing on SunOS 4, even with gcc. Some of our code
71 now has C89-based assumptions, like free(NULL) being well defined,
72 that will probably frustrate any attempts to run this code under SunOS
73 4 or other pre-C89 systems.
75 * Some new code, bug fixes, and cleanup for IPv6 support. Most of the
76 code should support IPv6 transparently now. The RPC code (and
77 therefore the admin system, which is based on it) does not yet
78 support IPv6. The support for Kerberos 4 may work with IPv6 in very
79 limited ways, if the address checking is turned off. The FTP client
80 and server do not have support for the new protocol messages needed
81 for IPv6 support (RFC 2428).
83 * We have upgraded to autoconf 2.52 (or later), and the syntax for
84 specifying certain configuration options have changed. For example,
85 autoconf 2.52 configure scripts let you specify command-line options
86 like "configure CC=/some/path/foo-cc", so we have removed some of
87 our old options like --with-cc in favor of this approach.
89 * The client libraries can now use TCP to connect to the KDC. This
90 may be necessary when talking to Microsoft KDCs (domain controllers),
91 if they issue you tickets with lots of PAC data.
93 * If you have versions of the com_err or ss installed locally, you can
94 use the --with-system-et and --with-system-ss configure options to
95 use them rather than using the versions supplied here. Note that
96 the interfaces are assumed to be similar to those we supply; in
97 particular, some older, divergent versions of the com_err library
98 may not work with the krb5 sources. Many configure-time variables
99 can be used to help the compiler and linker find the installed
100 packages; see the build documentation for details.
102 * The AES cryptosystem has been implemented. However, support in the
103 Kerberos GSSAPI mechanism has not been written (or even fully
104 specified), so it's not fully enabled. See the documentation for
107 Major changes listed by ticket ID
108 ---------------------------------
110 * [492] PRNG breakage on 64-bit platforms no longer an issue due to
111 new PRNG implementation.
113 * [523] Client library is now compatible with the RC4-based
114 cryptosystem used by Windows 2000.
116 * [709] krb4 long lifetime support has been implemented.
118 * [880] krb5_gss_register_acceptor_identity() implemented (is called
119 gsskrb5_register_acceptor_identity() by Heimdal).
121 * [1087] ftpd no longer requires channel bindings, allowing easier use
122 of ftp from behind a NAT.
124 * [1156, 1209] It is now possible to use the system com_err to build
127 * [1174] TCP support added to client library.

136 * [1189, 1251] The KfM krb4 library source base has been merged.
138 * [1190] The default KDC master key type is now triple-DES. KDCs
139 being updated may need their config files updated if they are not
140 already specifying the master key type.
142 * [1190] The default ticket lifetime and default maximum renewable
143 ticket lifetime have been extended to one day and one week,
146 * [1191] A new script, k5srvutil, may be used to manipulate keytabs in
147 ways similar to the krb4 ksrvutil utility.

150 been integrated. Thanks to Ken Hornstein.
152 * [1343] The KDC now defaults to not answering krb4 requests.
154 * [1344] Addressless tickets are requested by default now.
156 * [1372] There is no longer a need to create a special keytab for
157 kadmind. The legacy administration daemons "kadmind4" and
158 "v5passwdd" will still require a keytab, though.
160 * [1377, 1442, 1443] The Microsoft set-password protocol has been
161 implemented. Thanks to Paul Nelson.
163 * [1385, 1395, 1410] The krb4 protocol vulnerabilities
164 [MITKRB5-SA-2003-004] have been worked around. Note that this will
165 disable krb4 cross-realm functionality, as well as krb4 triple-DES
166 functionality. Please see doc/krb4-xrealm.txt for details of the
169 * [1393] The xdrmem integer overflows [MITKRB5-SA-2003-003] have
172 * [1397] The krb5_principal buffer bounds problems
173 [MITKRB5-SA-2003-005] have been fixed. Thanks to Nalin Dahyabhai.
175 * [1415] Subsession key negotiation has been fixed to allow for
176 server-selected subsession keys in the future.
178 * [1418, 1429, 1446, 1484, 1486, 1487, 1535, 1621] The AES
179 cryptosystem has been implemented. It is not usable for GSSAPI,
182 * [1491] The client-side functionality of the krb524 library has been
183 moved into the krb5 library.
185 * [1550] SRV record support exists for Kerberos v4.
187 * [1551] The heuristic for locating the Kerberos v4 KDC by prepending
188 "kerberos." to the realm name if no config file or DNS information
189 is available has been removed.
191 * [1568, 1067] A krb524 stub library is built on Windows.

219 * [647] libtelnet/kerberos5.c no longer uses internal include files.
