Query: Not that great.

Reading the other reviews of this book I was expecting it to be fantastic. I was disappointed. The book is well written and provides a good overview. However, I was hoping that I could use this book to take me through a fairly complex RADIUS implementation using FreeRADIUS and LDAP. It was not at all adequate in that regard. The configuration examples are sparse and not explained in detail. I was left with a lot of questions about how the RADIUS software actually implements the standard. How user files are parsed, how attribute matching is done, what is actually checked and returned. Things like that were not covered at all. This is a good introduction to RADIUS, but if you have a real project to do you are still going to have to spend a lot of time digging for more info on the web or in poorly written documentation that is available out there. I would call this the best RADIUS book because it is the ONLY RADIUS book.
