PowerShell Script to Loop Over All Users in a Group


I'm running Windows 7 Professional.

I know how to get a list of all the users in a group:

$ou="User Groups"
$userADName="RRAS VPN SSL"
$user = [adsi] $userADPath

I tried iterating over that list, creating an [adsi] object for each:

$ou="User Groups"
$userADName="RRAS VPN SSL"
$user = [adsi] $userADPath
$user.Member| ForEach-Object {[adsi] ("ldap://proddc6.prod.root/" + $_)}

I was thinking of looping over the list of objects and fetching the email address and full name, then running some commands using that information. Instead, this produces the error:

The following exception occurred while retrieving member "PSComputerName": "Unknown error (0x80005000)"
    + CategoryInfo          : NotSpecified: (:) [format-default], ExtendedTypeSystemException
    + FullyQualifiedErrorId : CatchFromBaseGetMember,Microsoft.PowerShell.Commands.FormatDefaultCommand

How can I iterate over the list of users in a group, processing the email address and full name for each user?

You get this error because the LDAP path that you are sending to the loop is not right. You are pipeing $user.Member to the ForEach-Object, it sends all users and not one bye one.

So you are sending something like:

ldap://proddc6.prod.root/CN=User1,CN=Users,DC=prod,DC=root CN=User2,CN=Users,DC=prod,DC=root

I created this script based on yours, it do what you need: interate over the members of a group. Do what you want with the object $useradsi in the loop.

$ou="User Groups"
$userADName="RRAS VPN SSL"
$objADSI = [adsi]””
$domain = $objADSI.distinguishedname
$user = [adsi] $userADPath

foreach($child in $user.member) {
$useradsi = [adsi] "LDAP://$child"
