+krb5-strength 2.0 (2013-10-07)
+
+ Add support for the MIT Kerberos password quality plugin interface,
+ available in MIT Kerberos 1.9 and later, contributed by Greg Hudson
+ and MIT. Drop the patch for MIT Kerberos 1.4 (and hence support for
+ versions of MIT Kerberos prior to 1.9). A dictionary path set in
+ krb5.conf takes precedence over the dictionary path provided by MIT
+ Kerberos when the plugin is initialized, if both are set, to allow the
+ dict_path configuration setting to be used for other plugins while
+ using a separate dictionary for krb5-strength.
+
+ The default installation path for this plugin is now
+ /usr/local/lib/krb5/plugins/pwqual/strength.so (for both MIT and
+ Heimdal), assuming a --libdir setting of /usr/local/lib. This may
+ require updates to the Kerberos KDC configuration or moving the plugin
+ when upgrading from earlier versions.
+
+ Add support for building with TinyCDB and then checking passwords
+ against a CDB database. There is a new password_dictionary_cdb
+ krb5.conf configuration setting that configures a CDB directory to
+ use. The tests with a CDB dictionary are much simpler: passwords are
+ rejected if found in the dictionary either literally, with one or two
+ characters removed from the start or end, or with one character
+ removed from both the start and the end. Both a CrackLib and a CDB
+ dictionary can be specified to check both dictionaries. A new
+ cdbmake-wordlist utility (written in Perl) is included to ease the
+ process of creating a CDB database from a simple word list.
+
+ A minimum password length can now be enforced directly via the plugin
+ or external check program without relying on CrackLib. To set a
+ minimum password length, add a minimum_length setting to the
+ krb5-strength section of [appdefaults] in krb5.conf.
+
+ New boolean settings require_ascii_printable and require_non_letter
+ are supported in the krb5-strength setting of [appdefaults] in
+ krb5.conf. The former rejects passwords containing characters other
+ than printable ASCII characters (including space), and the latter
+ requires that passwords contain at least one character that is not a
+ letter (upper or lower case) or a space.
+
+ The plugin can now be configured without a dictionary, in which case
+ only checks for a password based on the principal and the simpler
+ checks available through the new configuration variables are done.
+ This mode is mostly useful for testing, since such simple checking can
+ more easily be done via less complex password strength configurations.
+
+ The check for passwords based on the principal now check for passwords
+ formed by reversing or adding numbers before and after each separate
+ component of the principal. This will catch passwords based on the
+ realm or components of the realm, which will often catch passwords
+ based on the name of the local institution.
+
+ The plugin now sets the Kerberos error message in the context to pass
+ error information, resulting in higher-quality error reporting in the
+ MIT Kerberos plugin.
CrackLib checks for passwords where a character is a simple increment
or decrement of the previous character. In previous versions, the
which tightens the check somewhat for shorter passwords and loosens it
considerably for longer passwords.
+ Expect the Heimdal password strength checking plugin header in
+ kadm5/kadm5-pwcheck.h instead of outside of the kadm5 directory. This
+ is the path used by current versions of Heimdal. Drop support for
+ older versions of Heimdal that don't install this header file.
+
+ Update to rra-c-util 4.9:
+
+ * Probe for Kerberos headers using file checks instead of compiles.
+ * Improve probe for the Heimdal libroken library.
+ * Always build with large file support.
+ * Conditionally call AM_PROG_AR for portability to new Autotools.
+
+ Update to C TAP Harness 2.2:
+
+ * Allow more easily running single programs under tests/runtests.
+ * Flush the output from the test harness after each test.

Support linking with the system CrackLib instead of the embedded and
stricter copy by passing --with-cracklib to configure.
