Authentication Hook

To use this hook, you must build a custom authentication scheme using the Authentication API. A custom authentication scheme can assume control over user disambiguation, authentication, and impersonation issues. A custom authentication scheme can accept or reject a user's authentication attempt, and can specify a numeric reason and a text message for doing so. The numeric reason and the text message are made available to the application so that the application can take the appropriate action. This enables the application to maintain communication with the authentication scheme until the user is finally authenticated.
