JDBC-Based Authentication

In the previous chapter, we saw how we can extend Spring Security to utilize our CalendarDao interface and our existing domain model to authenticate users. In this chapter, we will see how we can use Spring Security's built-in JDBC support. To keep things simple, this chapter's sample code is based on our Spring Security setup from Chapter 2, Getting Started with Spring Security. In this chapter, we will cover the following topics:

• Using Spring Security's built-in JDBC-based authentication support
• Utilizing Spring Security's group-based authorization to make administering users easier
• Learning how to use Spring Security's UserDetailsManager interface
• Configuring Spring Security to utilize the existing CalendarUser schema to authenticate users
• Learning how we can secure passwords using Spring Security's new cryptography module...
