Regular readers will know that I moved on from my role as community lead for OpenSSO some time ago, first to Huawei, then, a few months ago, to salesforce.com, blogging mostly at the Force.com blog. In that time, Forgerock have adopted OpenSSO, rechristening it OpenAM, and my ex-colleague Indira Thangasamy, Senior Quality Engineering Manager for OpenSSO, has been hard at work on his book on OpenAM.
Packt Publishing were kind enough to send me a review copy of OpenAM, and a very professional job it is. While I've not had a chance to read it in detail, what I have read so far has been excellent - Indira writes clearly, covering every aspect of OpenAM, from the basics of single sign-on to advanced topics such as integrating OpenAM with Google Apps and salesforce.com (yay!) and interacting with OpenAM via its RESTful identity web service interface.
I'll post a more thorough review once I'm done reading, suffice to say for now, if you're working with or evaluating OpenSSO/OpenAM, this should definitely be on your bookshelf! Click here to go to Packt's page for OpenAM.
