i need to grant permissions of a couple of local folders for a specific local group. I'm using System.Security.AccessControl.FileSystemAccessRule. And it looks like this:

$aclFolders =  Join-Path -Path $env:windir -ChildPath "\temp\"
$group = "sql\IIS_IUSRS"
$Acl = Get-Acl $aclFolders
$Ar = New-Object System.Security.AccessControl.FileSystemAccessRule($group, "FullControl", "ContainerInherit,ObjectInherit", "None", "Allow")
Set-Acl $aclFolders $Acl

sql\IIS_IUSRS is a local group If I run the script on it (or even with sql\Administrators) i get this:

Exception calling "SetAccessRule" with "1" argument(s): "Some or all identity references could not be translated." At C:\projects\dsc.quickstart\sitecore-web-role\install.ps1:16 char:1 + $Acl.SetAccessRule($Ar) + ~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : NotSpecified: (:) [], MethodInvocationException + FullyQualifiedErrorId : IdentityNotMappedException

I'm wondering if that function would only work with users and not also with groups. Thanks for your help in advance.

    Eventually it came up that the correct domain for local built-in groups is: BUILTIN\a-group and when running the script on BUILTIN\IIS_IUSRS it just works. Oct 25, 2018 at 8:38

On W10 systems rolled out in their own language it fails as well. "Everyone" is not translated to "Iedereen" So for standard SID's better Use the GUI

$acl = Get-Acl -Path <FolderName> 

$objSID = New-Object System.Security.Principal.SecurityIdentifier ("S-1-1-0")
$objUser = $objSID.Translate( [System.Security.Principal.NTAccount])
$Name = $objUser.Value

Write-Host $Name #will show translated sid in local language
        $InheritanceFlag = @([System.Security.AccessControl.InheritanceFlags]::ContainerInherit,[System.Security.AccessControl.InheritanceFlags]::ObjectInherit)
        $PropagationFlag = [System.Security.AccessControl.PropagationFlags]::None
        $rule = New-Object System.Security.AccessControl.FileSystemAccessRule ("$Name","FullControl",$InheritanceFlag,$PropagationFlag,"Allow")
        Set-Acl -Path <FolderName> -AclObject $acl -Verbose -ErrorAction Stop
