It is not every day I need to add users in bulk to Active Directory, but when I do, I usually need to write a script that can be quiet time-consuming. It just so happened that I came across a tool to make this process a little easier today. Its name is ADUC Tool, and it allows you to import users from a CSV file or build them based on pre-configured settings. The tool is based in PowerShell, but it has a GUI. While this is a no-frills option, it is free and is very customizable for any organization.
