I wrote a scathing review of the 2nd edition - and justifiably so according to the author. So it is indeed a pleasure to see how the author has not only addressed the shortcomings of the presentation of the original publication but improved it dramatically, with new structure and diagrams that are clear and complement the text superbly.



My recommendation for future revisions of this book would be to also consider the standards that apply to Identity Management and the provisioning of identities within comsumer systems. For example, I notice that the is no reference at all to SPML in the book and all the examples assume either a custom or API interface.



This is a really good book and a pleasure to recommend to others.
