# Script Name: FixPermissions.ps1
# Version: 1.0
# Author: Sheridan Wendt
# Date: 9/26/2017
# Applies to: User Folders
#
# Description: This script will copy the permissions of a template folder 
# ($Template) then assign those permissions to a list of folders inside of a root 
# folder. It will also add an access rule ($AR) to the copied permissions, which 
# is useful to grant "Modify" access to the folder for a user that has the same 
# name as the $SubFolder.name (works only when the folder name is the same as the 
# username, such as a Home Drive.)
