Working with Active Directory in Powershell – Finding and exporting user information

Most of us work primarily with Active Directory Users and Computers, and for the most part this works fine. Sometimes though, its easier to do the things we need to do with PowerShell.

In this post, ill cover the basics of using PowerShell with Active Directory to get user information.

Connecting to Active Directory
If you are working on a Server with an Active Directory Role (Domain Controller etc.) you will already have all the tools you need. You can either open the Active Directory Module for PowerShell from start.

Or you can open PowerShell and add the Active Directory Module

Import-Module Active Directory

If you are working on a machine which is not a Server with an AD role, you will need to be on a machine which is a member of the domain you want to query and has the ‘Remote Server Administration Tools’ or ‘RSAT’ installed.

For more information on installing RSAT, see this post on TechNet

Once you have RSAT installed, ensure you have the Active Directory Module for PowerShell installed.



Testing the Connection to Active Directory.
Once you have PowerShell open, you can check that you can communicate Active Directory easily using the command


This will simply connect to Active Directory and output some basic details above the domain.


The Get-ADUser Commandlet
The only cmdlet we’ll use here is ‘Get-ADUser’

As with every PowerShell CommandLet you can use the Get-Help to get detailed information on the parameters you can use.

Get-Help Get-ADUser

You can also use -Examples to get some sample code

Get-Help Get-ADUser -Examples

Finding Users
Firstly, we can use the Get-ADUser cmdlet to retrieve all the users in the Domain:

Get-ADUser -Filter *

This will retrieve every user in Active Directory and output this as list.

However, this isn’t very useful, as it most likely won’t contain the attributes you need.

By default, only a small set of attributes are retrieved. You can specify the attributes to be retrieved using:

-Properties *

This will add every property for a user, but you can then us the ‘select’ option to display only the attributes you want.

| select <attributeName>, <attributeName2>
Get-ADUser -Filter * -Properties * | select sAMAccountName, givenName, surname

You can select as many attributes as you want, but if you add more than 4, the way the information is displayed will change from a tabular format to a 1 line per attribute.


Exporting the retrieved information
your probably querying active directory in order to do something with the information, and for that you may want the data exported into a usable format. You can export to a csv file by adding

| Export-Csv "C:\pathtoexportto\filename.csv" -noType
Get-ADUser -Filter * | select sAMAccountName, givenName, surname

Filtering which OU’s to query
So far we have only queried the full domain. To choose where the base of the query should be, you can add the Property -SearchBase

-SearchBase "OU=nameofou,DC=domain,DC=local"
Get-ADUser -Filter * -SearchBase "OU=Staff,OU=Users,OU=Salamander-Sims,DC=salamandertest,DC=co,DC=uk" | select sAMAccountName

Find a specific user
If you want to select a user specifically you can specify the parameter -Identity followed by the account name

Get-ADUser -Identity myusername

Adding filters based on attributes

You can also filter users using their attributes with the Filter Parameter

Get-ADUser -Filter {givenName -eq "Ben"
Get-ADUser -Filter {(givenName -eq "John") -and (sn -eq "Smith")}

You can also use the -like parameter when filtering. Here we query any user where they have an email address.

Get-ADUser -Filter {mail -like "*"}
