Setting NTFS Permissions With Powershell

Question

Using the following powershell I have set the NTFS Permissions for a folder for full control. For some reason this is only applying to the folder and not its contents. I followed the instructions located here

$username = "exampleuser"

$permissionArgs = "domain\$username", "FullControl", "allow"
$permissionRule = New-Object System.Security.AccessControl.FileSystemAccessRule $permissionArgs
$acl = Get-Acl 'C:\Users\username1\Desktop\TESTING2'
$acl.SetAccessRule($permissionRule)
Set-ACL -Path 'C:\Users\username1\Desktop\TESTING2' -AclObject $acl

When I use CACLS to see the permissions I get the following output. (usernames+domain blurred)

Can anyone advise how to make the first user listed have the same permissions as the last?

Solution

You need to include the inheritance parameter while definig the ACL rule like the below one.

$Folderpath='Destination Folder'
$user_account='User Acccount'
$Acl = Get-Acl $Folderpath
$Ar = New-Object system.Security.AccessControl.FileSystemAccessRule($user_account, "FullControl", "ContainerInherit, ObjectInherit", "None", "Allow")
$Acl.Setaccessrule($Ar)
Set-Acl $Folderpath $Acl

Hope this HElps.
