Dictionary Password Validator

The Dictionary Password Validator determines whether a proposed password is acceptable based on whether the given password value appears in a provided dictionary file.

A large dictionary file is provided with the server, but the administrator can supply an alternate dictionary. In this case, then the dictionary must be a plain-text file with one word per line.

Parent

The Dictionary Password Validator object inherits from Password Validator.
