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

To learn about CIDR and subnetting, the answer is in this thread on SF. It has great answers that explain everything you want to know about :) – petrus Aug 12 '12 at 20:21

Well I'm more interested in the theory of it, so how it works and so on... cause I'm missing the theory not the practice :D – MixturaDementiae Aug 12 '12 at 21:04

What you are probably looking for is Samba 4:

Something like FreeIPA is the closest parallel to Active Directory on the Linux side, as it combines DNS, directory services, centralized authentication, etc.
