This tutorial serves as an introduction to the Java platform authentication and authorization service, known as JAAS. In addition to becoming familiar with all the essential components of JAAS, you've had a hands-on introduction to several login modules and learned the basics of working with JAAS on the command line. You've also had the opportunity to run an actual JAAS application and try out several successful and unsuccessful configurations.

At the close of this tutorial, you should find yourself well poised for continuing exploration of the JAAS programming framework. Combining JAAS's authentication and authorization techniques with the cryptographic technologies discussed in Part 1 of this tutorial will enable you to architect and implement a vast array of application security solutions. To further your learning, you should continue to play with JAAS, exploring a number of different login modules, configurations, and security scenarios.
