PowerShell Cmdlet for Unix Attributes

This is a PowerShell cmdlet for adding Unix attributes to a Windows Active Directory user. It is especially useful with Windows Server 2016 which removed the NIS server and the GUI tools for managing the Unix attributes.

It will automatically find and assign the next available UID.

For direct download of a Windows installer, see bottom of page.


Add-UnixAttributes -sAMAccountName [-NISDomain] [-GIDNumber] [-LoginShell] [-UnixHomeDirectory]


  • sAMAccountName: the username to add Unix Attributes to.
  • NISDomain: the NIS Domain to use (default: int).
  • GIDNumber: the primary GID to assign (default: 750)
  • LoginShell: the login shell to assign (default: /bin/bash)
  • UnixHomeDirectory: the home directory to set (default: /home/<sAMAccountName>)


The script is already written in PowerShell, so you do not have to build it.


To import the script in your current session: `Import-Module Add-UnixAttributes.psm1`. Alternarively, run it from its directory.

You must use an Administrator shell for it to work.

You need to have PowerShell ActiveDirectory module installed (part of RSAT).


You can use the provided NSIS script to build a GUI installer with your DLL. NSIS is available for Windows and Linux, see http://nsis.sourceforge.net (on Linux, be sure to check with your distro first):

  • From the top level directoy of the repo, call makensis Add-UnixAttributes.nsis.
