One of the biggest concerns we have while using our computer is privacy and if you are running a company its importance is undefinable. There are quite a few methods to ensure privacy in Windows but if you don’t want anyone else to log in to your server, in that case, most companies adopt Microsoft Active Directory. With this, no one other than you and your team can log in to your system.

Microsoft Active Directory is nothing but a database built by Microsoft. You need to access it on a device running Windows Server and it will act as a domain controller. All the users in the Windows domain network need to communicate with the domain controller in order to log in to the server.

However, Microsoft Active Directory is not the only directory software in the market. Therefore, in this article, we are going to find some of the best free Microsoft Active Directory alternatives in the market.
