krb5-strength provides a password quality plugin for the MIT Kerberos KDC (specifically the kadmind server), an external password quality program for use with Heimdal, and a per-principal password history implementation for Heimdal. Passwords can be tested with CrackLib, checked against a CDB or SQLite database of known weak passwords with some transformations, checked for length, checked for non-printable or non-ASCII characters that may be difficult to enter reproducibly, required to contain particular character classes, or any combination of these tests.
