# Program Name: AutoUserADCreator
# Purpose of script: Create a batch set of user's within an existing OU using a CSV file containing a list of predetermined users and OU's.
# Other Notes: My job is to create simple checks to avoid issues such as duplicate users.
# Other Notes: Credit is given for parts I have contributed to the script.

# Import required PowerShell modules
import-module ActiveDirectory

#Specify User Principal Name (Active Directory Domain Forest Name) (Rayyan Modified to allow for user to enter their own forest name)
$UPN = Read-Host -Prompt "Please enter the Active Directory Forest name (example.com)"

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

# Check if CSV file exists with the path specified by the end-user
# If so, error out the program with generic error stating so. (RAYYAN Contribution)
# This uses the "Test-Path" cmdlet which tests if the path actually exists and can be read by the system.
