+ * This implementation of an AuthenticationComponent can be configured to accept or reject all attempts to login.
+ * 
+ * This only affects attempts to login using a user name and password.
+ * Authentication filters etc. could still support authentication but not via user names and passwords.
+ * For example, where they set the current user using the authentication component.
+ * Then the current user is set in the security context and asserted to be authenticated.
+ * 
+ * By default, the implementation rejects all authentication attempts.
