I'll have to admit that my primary reason for reading this book was not to kindle my knowledge of Oracle products, but rather get a picure of the IAM world. That proved a bit difficult, because it was not clear how the O-IAM model connected to the non-vendor-specific side of things. Not very suprising, but the foreword do describe the book as definitive guide. I'd recon the book would have been better with a "middle tier" of conceptual IAM.
