Alternatives to Microsoft Active Directory: Do you want anyone else to be able to log in to your Windows operating system other than you? The Active Directory was designed specifically for this purpose: to determine if the person entering your system is an ordinary user or the system administrator. This protects your system from unauthorized log-in attempts.
Active Directory is a special-purpose database intended for Microsoft Windows domain networks. Most Windows server operating systems include it as a set of processes and services. The domain controller is a computer that runs Active Directory Domain Services and checks and approves all users and machines in a Windows domain network.
This aids in the assignment and application of security codes to all machines, as well as in the installation or updating of software. As a result, when a user attempts to log in to your Windows domain machine, Active Directory authenticates the password supplied and distinguishes between a system administrator and an ordinary user.
Active Directory is particularly designed to read a high number of changes and updates made to your machine. There are several third-party alternatives to Microsoft Active Directory that do the same task but offer different capabilities. We’ll walk you through the best Microsoft Active Directory alternatives in this post to help you make an informed decision.
