O'Reillys Radius Book - Worth buying

[Jacob Jarick]

Hi, Im just getting started with freeradius (trying to nut out dynamic
vlans atm) and I was wondering if this book would be a worth while
purchase.

I had a great experience with O'reillys bind and perl cookbook books.
Have any FR users used this book and if so your comments would be
appreciated.
