This is not a rocket science thing since there are apparently multiple ways to do this but I had a specific requirement to quickly get a list of users for a group but only list specific properties which include the “Title” property that is not available using the AccountManagement namespace.

So without mush further ado… here is a simple script that works for me.

# Read the input parameters $GroupName
param([string] $GroupName = $(throw write-host "Please specify the group name." -Foregroundcolor Red))

$Recurse = $true

$OutputFile = "GroupUsers.csv"
Add-Type -AssemblyName System.DirectoryServices.AccountManagement
$ct = [System.DirectoryServices.AccountManagement.ContextType]::Domain
$group=[System.DirectoryServices.AccountManagement.GroupPrincipal]::FindByIdentity($ct, $GroupName)
$members = $group.GetMembers($Recurse)

$columnNames = "Name,Title,Description"
$columnNames | Out-File -FilePath $OutputFile -Encoding 'UTF8'
foreach($user in $members){
    $DE = $user.GetUnderlyingObject()
    $output = $user.name + "," + $DE.title + "," + $user.description

    Write-Host $output
    $output | Out-File -FilePath $OutputFile -Encoding 'UTF8' -append
    $output = ""
}

In order to get to the ‘Title’ property I use the ‘GetUnderlyingObject’ method to get the DirectoryEntry object which do have the ‘Title’ property. This way it makes it possible to access any/all the ‘forgotten’ properties which they never implemented in the new namespace.
Additionally it also save the output to a CSV file.
