23 Building and Installing Kerberos 5
24 ----------------------------------
26 The first file you should look at is doc/install-guide.ps; it contains
27 the notes for building and installing Kerberos 5. The info file
28 krb5-install.info has the same information in info file format. You
29 can view this using the GNU emacs info-mode, or by using the
30 standalone info file viewer from the Free Software Foundation. This
31 is also available as an HTML file, install.html.
33 Other good files to look at are admin-guide.ps and user-guide.ps,
34 which contain the system administrator's guide, and the user's guide,
35 respectively. They are also available as info files
36 kerberos-admin.info and krb5-user.info, respectively. These files are
37 also available as HTML files.
39 If you are attempting to build under Windows, please see the
40 src/windows/README file.
45 Please report any problems/bugs/comments using the krb5-send-pr
46 program. The krb5-send-pr program will be installed in the sbin
47 directory once you have successfully compiled and installed Kerberos
48 V5 (or if you have installed one of our binary distributions).
50 If you are not able to use krb5-send-pr because you haven't been able
51 compile and install Kerberos V5 on any platform, you may send mail to
54 Please keep in mind that unencrypted e-mail is not secure. If you need
55 to report a security vulnerability, or send sensitive information,
56 please PGP-encrypt it to krbcore-security@mit.edu.
58 You may view bug reports by visiting

62 and logging in as "guest" with password "guest".
67 The Data Encryption Standard (DES) is widely recognized as weak. The
68 krb5-1.7 release contains measures to encourage sites to migrate away
69 from using single-DES cryptosystems. Among these is a configuration
70 variable that enables "weak" enctypes, which defaults to "false"
71 beginning with krb5-1.8.

86 * Fix MITKRB5-SA-2011-006 and MITKRB5-SA-2011-007 KDC denial of
87 service vulnerabilities [CVE-2011-1527 CVE-2011-1528 CVE-2011-1529
90 * Update the Fortuna implementation to more accurately implement the
91 description in _Cryptography Engineering_, and make it the default
94 * Add an alternative PRNG that relies on the OS native PRNG.
98 * Add the ability for GSSAPI servers to use any keytab key for a
99 specified service, if the server specifies a host-based name with no
102 * In the build system, identify the source files needed for
103 per-message processing within a kernel and ensure that they remain
106 * Allow rd_safe and rd_priv to ignore the remote address.
108 * Rework KDC and kadmind networking code to use an event loop
111 * Add a plugin interface for providing configuration information.
113 Administrator experience:
115 * Add more complete support for renaming principals.
117 * Add the profile variable ignore_acceptor_hostname in libdefaults. If
118 set, GSSAPI will ignore the hostname component of acceptor names
119 supplied by the server, allowing any keytab key matching the service
122 * Add support for string attributes on principal entries.
124 * Allow password changes to work over NATs.
128 * Add the DIR credential cache type, which can hold a collection of
131 * Enhance kinit, klist, and kdestroy to support credential cache
132 collections if the cache type supports it.
134 * Add the kswitch command, which changes the selected default cache
137 * Add heuristic support for choosing client credentials based on the
140 * Add support for $HOME/.k5identity, which allows credential choice
141 based on configured rules.
143 * Add support for localization. (No translations are provided in this
144 release, but the infrastructure is present for redistributors to
149 * Make PKINIT work with FAST in the client library.
