029 * The default configuration for web security. It relies on Spring Security's
030 * content-negotiation strategy to determine what sort of authentication to use. If the
031 * user specifies their own {@link WebSecurityConfigurerAdapter}, this will back-off
032 * completely and the users should specify all the bits that they want to configure as
033 * part of the custom security configuration.
