* This validator checks the password against a policy named "passwordpolicy" from the validator configuration.
* If no such entry is available, it validates that the password has a minimum of 6 and maximum of 30 chars, which
* was the GateIn behavior before the introduction of this validator.
*
* The entries in the configuration file should look like this:
* <pre>
* gatein.validators.passwordpolicy.length.min=5
* gatein.validators.passwordpolicy.length.max=50
* gatein.validators.passwordpolicy.regexp=...
* gatein.validators.passwordpolicy.format.message=Minimum 5 chars, max 50 chars, upper/lower case required, number required.
* </pre>
