Setting folder permissions

NewWorldMan

I've been experimenting with a couple of scripts to set folder permissions.

I've tried this from here

$acl = Get-Acl c:\temp
$permission = "domain\user","FullControl","Allow"
$accessRule = New-Object System.Security.AccessControl.FileSystemAccessRule $permission
$acl.SetAccessRule($accessRule)
$acl | Set-Acl c:\temp

and this from here

#ChangeACL.ps1
$Right="FullControl"

#The possible values for Rights are
# ListDirectory, ReadData, WriteData
# CreateFiles, CreateDirectories, AppendData
# ReadExtendedAttributes, WriteExtendedAttributes, Traverse
# ExecuteFile, DeleteSubdirectoriesAndFiles, ReadAttributes
# WriteAttributes, Write, Delete
# ReadPermissions, Read, ReadAndExecute
# Modify, ChangePermissions, TakeOwnership
# Synchronize, FullControl

$StartingDir=Read-Host "What directory do you want to start at?"
$Principal=Read-Host "What security principal do you want to grant" `
"$Right to? `n Use format domain\username or domain\group"

#define a new access rule.
#note that the $rule line has been artificially broken for print purposes.
#it needs to be one line. the online version of the script is properly
#formatted.
$rule=new-object System.Security.AccessControl.FileSystemAccessRule
($Principal,$Right,"Allow")

foreach ($file in $(Get-ChildItem $StartingDir -recurse)) {
$acl=get-acl $file.FullName

#Add this access rule to the ACL
$acl.SetAccessRule($rule)

#Write the changes to the object
set-acl $File.Fullname $acl
}

For the second one I get this error when trying to apply it to an inetpub folder:

Exception calling "SetAccessRule" with "1" argument(s): "Some or all identity references could not be translated."
At C:\Documents and Settings\kmcfarlane\My Documents\Development\ChangeACL.ps1:29 char:21
+ $acl.SetAccessRule( <<<< $rule)
Set-Acl : The security identifier is not allowed to be the owner of this object.
At C:\Documents and Settings\kmcfarlane\My Documents\Development\ChangeACL.ps1:32 char:10
+ set-acl <<<< $File.Fullname $acl

For the first script I just get the first part of that error. Any ideas?

This one is shorter...

Works for me.

So, does "domain\user" exist in your environment? That syntax supposes
that you are adding a *domain* account with that username.
