+=item cracklib_maxlen
+
+Normally, all passwords are checked with CrackLib if a CrackLib dictionary
+is defined. However, CrackLib's rules were designed for a world in which
+most passwords were four to eight characters long, and tends to spuriously
+reject a lot of passphrases. If this option is set to something other
+than its default of 0, passwords longer than that length bypass CrackLib
+checks. (Using a SQLite dictionary for longer passwords is strongly
+recommended.)
+
+=item minimum_different
+
+If set to a numeric value, passwords with fewer than this number of unique
+characters will be rejected. This can be used to reject, for example,
+passwords that are long strings of the same character or repetitions of
+small numbers of characters, which may be too easy to guess.
