Set-ACL problem passing a string instead of an object variable...

Hi,

I have a problem that's giving me a head-ache but hopefully is simple to someone out there with a bigger brain than mine.

Basically I have script for new user creation that picks up a variable $logonname which is a text string the first initial and whole last name of the user being created, thus for the new user John Smith, the $logonname is JSmith. As the variable name suggests this is the Windows logon name for the user.

All this works fine, but later in the script I try to create the user's home and profile folders and assign permissions, as below:

$profilepath = "\\domain.com\profiles\$logonname"

$profilepathV2 = "\\domain.com\profiles\$logonname.V2"

$homepath = "\\domain.com\home\$logonname"

New-Item -type directory -Path $profilepath

New-Item -type directory -Path $profilepathv2

New-Item -type directory -Path $homepath

$Acl = Get-Acl $profilepath 

$Ar = New-Object system.security.accesscontrol.filesystemaccessrule("$logonname","FullControl","ContainerInherit, ObjectInherit", "None", "Allow") 

$Acl.AddAccessRule($Ar) 

Set-Acl $profilepath $Acl 

$Acl = Get-Acl $profilepathv2 

$Ar = New-Object system.security.accesscontrol.filesystemaccessrule("$logonname","FullControl","ContainerInherit, ObjectInherit", "None", "Allow") 

$Acl.AddAccessRule($Ar) 

Set-Acl $profilepathv2  $Acl

$Acl = Get-Acl $homepath

$Ar = New-Object system.security.accesscontrol.filesystemaccessrule("$logonname","FullControl","ContainerInherit, ObjectInherit", "None", "Allow") 

$Acl.AddAccessRule($Ar) 

Set-Acl $homepath $Acl
