I read this article some weeks ago and had a chance to look more into some of these tools and to try several of them. Yes, it looks interesting but sometimes this command line tools are a bit complicated to use. As for me - I’m into easier solutions. For active directory management my personal favourite is active administrator. First of all it’s a gui solution so you can use it intuitively without reading manuals about command line keys and parameters. And I really love that this tool covers the most important active directory administration tasks. For more info about active administrator you can go to http://www.scriptlogic.com I hope it was useful.
