modifications made to the embedded CrackLib and what problems one may
encounter using an unmodified version.
+ * Update to CrackLib 2, which is currently shipped in Debian. This
+ requires testing to confirm that the on-disk data format is still the
+ same.
+
+ * Feed back modifications to CrackLib 2 to allow a program to use a
+ custom set of rules, which would allow us to stop embedding our own
+ copy of CrackLib customized to add additional rules.
+
* The kadmind patch needs to abort kadmind startup if the plugin could
not be loaded, or at least needs to reject every password.
