I have taken this script originally from https://gallery.technet.microsoft.com/scriptcenter/New-User-Creation-tool-14fa73cd. This script was originally written by Rich Prescott (https://social.technet.microsoft.com/profile/rich%20prescott/) Then there were several modifications made, so we can add unix attributes such as UID and GID when we are creating this user.

##Installing Identity Management for Windows Server 2012

To install or remove Identity Management for UNIX by using Dism.exe On a domain controller that runs Windows Server 2012 R2 or Windows Server 2012, Right-click Windows PowerShell and click Run as Administrator .

Type one of the following, and then press ENTER:

To install the administration tools for Identity Management for UNIX

Dism.exe /online /enable-feature /featurename:adminui /all

To remove the administration tools for Identity Management for UNIX

Dism.exe /online /disable-feature /featurename:adminui

##Note

This installs or removes only the administration tools. Using Dism.exe, Server for NIS and Password Synchronization must be installed separately.

Dism.exe /online /enable-feature /featurename:nis /all to install Server for NIS.
Dism.exe /online /disable-feature /featurename:nis to remove Server for NIS.
Dism.exe /online /enable-feature /featurename:psync /all to install Password Synchronization.
Dism.exe /online /disable-feature /featurename:psync to remove Password Synchronization.

A restart of the computer is required when you install or remove Identity Management for UNIX. The /quiet parameter restarts the computer automatically after installation or removal is finished.
