/**
 * Class that implements configuration of the Spring Security for RESTful interface
 * of the PowerAuth 2.0 Server. This configuration is prepared in such a way that it
 * does not apply to the SOAP interface - only to REST.
 *
 * If a configuration "powerauth.service.restrictAccess" suggests that access should be
 * restricted, HTTP Basic Authentication is used for RESTful API endpoints. Username and
 * passwords can be set in the "pa_integration" table.
