/**
 * Enable OAuth2 Single Sign On (SSO). If there is an existing
 * {@link WebSecurityConfigurerAdapter} provided by the user and annotated with
 * {@code @EnableOAuth2Sso}, it is enhanced by adding an authentication filter and an
 * authentication entry point. If the user only has {@code @EnableOAuth2Sso} but not on a
 * WebSecurityConfigurerAdapter then one is added with all paths secured and with an order
 * that puts it ahead of the default HTTP Basic security chain in Spring Boot.
