Enable OAuth2 Single Sign On (SSO). If there is an existing WebSecurityConfigurerAdapter provided by the user and annotated with @EnableOAuth2Sso, it is enhanced by adding an authentication filter and an authentication entry point. If the user only has @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.
