The Script you have gives you the path with ANY permissions that aren't inherited. Using the Get-ACL, it looks at anything that has permissions assigned to the folder. So it's looking in there and telling you "This path has somebody with permissions that are not inherited."

I take it the question you are wanting to answer is: WHO has permissions that are not inherited?

I could benefit from this. A simple ACL auditing script could come in handy.

The Above script outputs a csv file (named myFolderInheritance.csv) that looks something like the following when run against C:\Program Files... (this is just a snippet)

C:\Program Files\Internet Explorer, CREATOR OWNER,False
C:\Program Files\Internet Explorer, NT AUTHORITY\SYSTEM,False
C:\Program Files\Internet Explorer, NT AUTHORITY\SYSTEM,False
C:\Program Files\Internet Explorer, BUILTIN\Administrators,False
C:\Program Files\Internet Explorer, BUILTIN\Administrators,False
C:\Program Files\Internet Explorer, BUILTIN\Users,False
C:\Program Files\Internet Explorer, BUILTIN\Users,False
C:\Program Files\Internet Explorer, NT SERVICE\TrustedInstaller,False
C:\Program Files\Internet Explorer, NT SERVICE\TrustedInstaller,False
C:\Program Files\Internet Explorer, APPLICATION PACKAGE AUTHORITY\ALL APPLICATION PACKAGES,False
C:\Program Files\Internet Explorer, APPLICATION PACKAGE AUTHORITY\ALL APPLICATION PACKAGES,False
C:\Program Files\Internet Explorer, APPLICATION PACKAGE AUTHORITY\ALL RESTRICTED APPLICATION PACKAGES,False
C:\Program Files\Internet Explorer, APPLICATION PACKAGE AUTHORITY\ALL RESTRICTED APPLICATION PACKAGES,False

I did not have time yesterday to research an answer.

$nonInherited|out-file -FilePath $outFile


write-host "Done."

These works to certain extend of what I am looking for, but it needs some tweaking to work the way I am expecting the result.
Thanks!

How are you wanting the result to look?

The script doesn't appear to be showing false on non-inheritance. There either True or False for every member of the folder regardless of their inheritance.

I am looking into this post right now as it was brought up in Spiceworks.
It shows the result I am hoping for where non-inheritance = false and inherited = true.

Ah, okay. I thought you wanted to only see the ones where Inherited=False...

So you want to see everything, and whether or not it is inherited?

Edit: Also for the CSV File generated, the layout is

Folder, User, Is Inherited

Is Inhertied is True or False.
