There is probably more information in Apple's online Lion Server documentation than in this book. Certainly there is very little in the way of serious trouble shooting or useful maintenance hints and tips - and as you'll inevitably have problems with Lion Server you'll be lost pretty quickly relying on this book. This is really just a reasonably methodical but somewhat basic 1st time set up manual for Lion Server, nothing particularly in-depth and not really something to help you day to day in keeping the beast up and running. Tech books are pricey but I expected more from this. Pretty expensive for what it is.
