-It's important to note that authorization claims will be included with the Access token. Why is this important? Well, let's say that authorization claims(e.g user privileges in the database) are changed during the life time of Access token. Those changes will not become effective until new Access token is issued. In most cases this is not big issue, because Access tokens are short-lived. Otherwise go with the opaque token pattern.
