I'm mainly a developer, who recently took a liking to Servers.
Most of my tinkering has been with Microsoft Windows Server 2003/2008, but I'd like to go down the rabbit hole and see what things Linux offers.
For example, MS has Active Directory - does Linux handle something like this? What do they have?
I'm an absolute beginner to Linux sysadmin (I've used Linux normally as an end user though), what book and distro would you recommend I start with?
This is just for hobby and to broaden my knowledge because I love learning. :)
Thank you for your time.
