  This service allows plugins to validate passwords based on a common policy.
 
  This is a "bridge service", i.e. facade with no
  real functionality that just calls the actual password validation plugin
  APIs. This serive is needed by other plugins to call into the password
  validation plugins and thus overcome the limitation that only the server
  can call plugins.
