# Purpose of script: Create a batch set of OU' using a CSV file within an existing Active Directory Forest.
# Extra Notes: Modify line 37 with appropriate domain info. (AlphaDelta.com is used in this scenario)

#Import the Active Directory module to allow modifcations to the forest.
import-module ActiveDirectory

#Get user to specify path of the CSV file containing OU names to be added into the Active Directory.
$fpath = Read-Host -Prompt "Please enter the path to your CSV file containing OU info to be added within the Active Directory Domain Forest"

# Check if the CSV file exists
if (Test-Path $fpath) {
    # Display path to file given by end-user
    echo $fpath

# Display path to file given by end-user
echo $fpath

#Import OU info from CSV file.

#Create OU's within the Active Directory forest by looping throughout each row within the CSV file.
