Add multiple users to multiple groups in AD using PowerShell

Get-ADUser -SearchBase ‘OU=Users,OU=Robnet,DC=robnet,DC=local’ -Filter * | % {Add-ADGroupMember -Identity ‘Script Test Group’ -Members $_ } 

Get-ADUser -SearchBase ‘OU=Users,OU=Robnet,DC=robnet,DC=local’ -Filter * | % {Add-ADGroupMember -Identity ‘Script Test Group2’ -Members $_ } 

Get-ADUser -SearchBase ‘OU=Users,OU=Robnet,DC=robnet,DC=local’ -Filter * | % {Add-ADGroupMember -Identity ‘Script Test Group3’ -Members $_ } 

# Put user out side like this
 $Users = @("Ryan Chau","Robin Clarke")

# OR you can put it in a txt file, your choice
 # $Users = Get-Content "B:\users.txt"

$Groups = Get-Content "B:\Groups.txt"
foreach ($User in $Users){
 foreach ($Group in $Groups)
 {
 $Sam = (Get-ADUser -Filter {Name -like $User}).SamAccountName
 write-host "Added $User ID: $Sam to $Group"
Add-ADGroupMember -Identity $Group -Members $Sam
 }

1. Robin –
   Great blog. This is Ryan from Toronto. I just want to add my 2 cent and hope that help few IT mates out there. Nothing wrong with your command, you just add 1 user to multiple groups with that command btw. But I’ve using scripting for this kind of request for a while. “Multiple Users to Multiple Groups.”

   # Put user out side like this
   $Users = @(“Ryan Chau”,”Robin Clarke”)

   # OR you can put it in a txt file, your choice
   # $Users = Get-Content “B:\users.txt”

   $Groups = Get-Content “B:\Groups.txt”
   foreach ($User in $Users){
   foreach ($Group in $Groups)
   {
   $Sam = (Get-ADUser -Filter {Name -like $User}).SamAccountName
   write-host “Added $User ID: $Sam to $Group”
   Add-ADGroupMember -Identity $Group -Members $Sam
   }
   }

   Have a good day,
   Ryan Chau

3. I modified Ryan’s script a bit to select users based on OU:
   #–Define variables–
   #Set OU
   $userou = “OU=Training,OU=Company,OU=Employees,DC=contonso,DC=local”
   #Read users from OU
   $Users = Get-ADUser -SearchBase $userou -Filter *
   #Set source file with groups, 1 group per line
   $GroupsSourcefile = “\\server.contoso.local\share$\Groups.txt”

   #Add users to groups
   $Groups = Get-Content $GroupsSourcefile
   foreach ($User in $Users){
   foreach ($Group in $Groups)
   {
   write-host “Added $User ID: $Sam to $Group”
   Add-ADGroupMember -Identity $Group -Members $User
   }
   }
