15.3. Authentication

Seam Security provides Java Authentication and Authorization Service (JAAS) based authorization features, providing a robust and highly configurable API for handling user authentication. If your authentication needs are not this complex, Seam also offers a simplified authentication method.

15.3.1. Configuring an Authenticator component

Note

If you use Seam's Identity Management features, you can skip this section — it is not necessary to create an authenticator component.
Seam's simplified authentication method uses a built-in JAAS login module (SeamLoginModule) to delegate authentication to one of your own Seam components. (This module requires no additional configuration files, and comes pre-configured within Seam.) With this, you can write an authentication method with the entity classes provided by your own application, or authenticate through another third-party provider. Configuring this simplified authentication requires the identity component to be configured in components.xml

#{authenticator.authenticate} is a method binding that indicates the authenticate method of the authenticator component will be used to authenticate the user.
