First this book explains how Pluggable Authentication Modules (PAM) simplify and standardize authentication in Linux. It shows in detail how PAM works and how it is configured. Then 11 common modules used across UNIX/Linux distributions are examined and explained, including all their parameters. Installation of third-party modules is discussed, and the development of new modules and PAM-aware applications is outlined. This book is for experienced system administrators and developers working with multiple Linux/UNIX servers or with both UNIX and Windows servers. It assumes a good level of admin knowledge, and that developers are competent in C development on UNIX-based systems.

1.0 out of 5 stars
Not much more than a MAN page.,
By Joshua (NH USA) - See all my reviews
Amazon Verified Purchase(What's this?)
This review is from: Pluggable Authentication Modules: The Definitive Guide to PAM for Linux SysAdmins and C Developers: A comprehensive and practical guide to PAM for Linux: how modules work and how to implement them (Paperback)
I did not gain anymore insight from this book than I already had from reading MAN pages and briefly researching on-line. The first 25 pages are basically history, file structure and an introduction with tips on how to compile from source. The other 75 pages are shallow descriptions of various modules, dumbed down examples so things don't get to complicated, and a short section that talks about development. There is absolutely no depth and very little useful information. I can't believe this is called a "definitive guide". If your work as a system administrator has brought you to considering this book chances are you probably already know more about PAM than you will gain from this book. I gave it one star because it is thin, lightweight, and it uses nice big fonts.

Useless for writing PAM modules,
By Homer Simpson (Los Gatos, CA USA) - See all my reviews
This review is from: Pluggable Authentication Modules: The Definitive Guide to PAM for Linux SysAdmins and C Developers: A comprehensive and practical guide to PAM for Linux: how modules work and how to implement them (Paperback)
If you are looking for a book to help you write a PAM module, this is definitely not it. There are all of 5 pages on the subject, and they go into much less detail than anything you can find on the web; no explanations for why things are the way they are are given.

The information contained in the book was easy to understand but it did not go into as much detail as I had hoped it would about what I was purchased it for.
