### Quick script for adding users in to groups based on a CSV input file
 
Start-Transcript "outputfileadd.log"
 
### CSV Variables
### CSV Format
### Header: UserSamAccountName,GroupSamAccountName
### Datalines: samaccountname,samaccountname
$csvfile = "\\filerepository\dfs\SCRIPT_REPOSITORY$\Organizational changes\orgchangeinput-add.csv"
 
### Get all changes from inputfile
$changes = Import-CSV $csvfile
 
### Get number of changes
$changescount = $changes.count
Write-host "Number of changes in csv: $changescount " -ForegroundColor green
 
Read-Host -Prompt 'You are about to add group memberships to AD. If you are sure, press ENTER to continue or close the script to cancel'
 
ForEach ($change in $changes){

  #Check for valid user
  if (Get-ADObject -Filter {objectClass -eq "user" -and samAccountName -eq $usersam}){
    #User is valid
    #now check for valid group
    if (Get-ADObject -Filter {objectClass -eq "group" -and samAccountName -eq $groupsam}){
      #Group is valid, we can add the user to the group
