User

Depending on further use-cases it can be refactored to an interface

The id is an unique identifier for an user. It isn't defined if it is an internal identifier or an identifier known by the user (like the user-name).
If users login e.g. via their e-mail address, it's possible to lookup an internal id in a custom implementation of LoginCredential or a bean which is in between (and LoginCredential doesn't get called directly in the 2nd case).

@Typed()
public class User implements Serializable
{
    private static final long serialVersionUID = -2234530384311026364L;

    private final String id;

    public User(String id)
    {
        this.id = id;
    }

    public String getId()
    {
        return id;
    }
}
