Many people see this diversity in Linux as a bad thing, but in reality that is what makes Linux so great. In Linux the user is in charged not the other way around. The…

Active Directory has changed a lot since it’s birth in 1999. The first time I used Active Directory was around 2004 on a Windows 2003 server. We had an Exchange 2003 server, and I remember using active directory to create e-mail accounts.
