I'm kinda new in the admin scenario. I'm looking for a good source where to study in deep what a domain is and how to manage it. The point is that I'm a tlc eng but I don't have any experience in it. At work I'm handling Active Directories, and I was wondering what is the correspondence in Linux, and where to get all the knowledge for it.
Any suggestion? Moreover do you have a good source where to study CIDR? :D thank you
