Creating groups in bulk

Previously, we have seen bulk creation of users using PowerShell. A similar requirement might come from creating security groups in bulk. The function given in the following code helps in creating groups in a bulk fashion. It creates a security group of a given scope (domain local, global, or universal) inside the default user's container by default. They can be created in different locations in the Active Directory structure by updating the $TargetOU variable's value with the DN of the OU where you want to create them:

Function Invoke-ADBulkGroup {
[CmdletBinding()]
Param(
  [Parameter(Mandatory=$true, Position = 0)]
  [String[]]$GroupName,
  [Parameter(Mandatory=$true, Position = 1)]
  [ValidateSet("DomainLocal","Global","Universal")]
  [string]$GroupScope
)
#Change the value of $TargetOU variable to the DN of the path  where you want the groups to be created
#If you leave it, it will create in default users container.
$TargetOU = (Get-ADDomain).UsersContainer
