Spring Security - Third Edition

CalendarUserAuthenticationProvider

Throughout the rest of this section, we are going to create a custom AuthenticationProvider object named CalendarUserAuthenticationProvider that will replace CalendarUserDetailsService. Then, we will use CalendarUserAuthenticationProvider to consider an additional parameter to support authenticating users from multiple domains. 

We must use an AuthenticationProvider object rather than UserDetailsService, because the UserDetails interface has no concept of a domain parameter.

Create a new class named CalendarUserAuthenticationProvider, as follows:

    //src/main/java/com/packtpub/springsecurity/authentication/    CalendarUserAuthenticationProvider.java    // … imports omitted ...    @Component public class CalendarUserAuthenticationProvider ...
