This chapter provides a discussion on the Sun Enterprise Authentication Mechanism (SEAM), as required by the exam. We'll go through a brief SEAM overview, detail some configuration issues that should be resolved before configuring SEAM, and then move on to SEAM configuration and administration using the SEAM GUI Administration Tool. As with much of the material in this book, this information has been condensed to include only the important topics you should know when preparing for the exam.
