A few years ago I had the pleasure to work with Rajesh Rajasekharan at Sun. He was an efficient trainer on Sun products and especially on Sun Directory Server. He recently joined ForgeRock and has started a series of blog posts and screen-casts on ForgeRock products and especially OpenDJ, but not only !
If you are getting started with the products or want to see demos of them, there’s no better place than to be on the “Learning Curve”
