1. Extend the Identity class looks like resonable, but how can this derived class be referenced as name of "identity" since the @Name("org.jboss.seam.security.identity") annotation is hard coded in the Identity class. 2. Indeed, add a property to the authenticator bean could solve this problem, but the property will not stay with Identity instance which is not acceptable by my case because of this property is used wildly after user autheticated. 3. My intention is embedding some fields to the Identity class without modidying the Identity class. Is this possible ? Sorry, I did not make my question clearly in the first post.
