Using Powershell to delete all users from the Portal

Question

Summary
This script will delete all users from the Portal except for Administrator and the Built-In Sync account.
Based on Markus's "Delete a User" script.
Useful when developing your system if you want to quickly clear out the data and start again.
set-variable -name URI -value "http://localhost:5725/resourcemanagementservice' " -option constant
function DeleteObject
PARAM($objectType, $objectId)
END
$importObject = New-Object Microsoft.ResourceManagement.Automation.ObjectModel.ImportObject
$importObject.ObjectType = $objectType
$importObject.TargetObjectIdentifier = $objectId
$importObject.SourceObjectIdentifier = $objectId
$importObject.State = 2
$importObject | Import-FIMConfig -uri $URI
if(@(get-pssnapin | where-object {$_.Name -eq "FIMAutomation"} ).count -eq 0) {add-pssnapin FIMAutomation}
$allobjects = export-fimconfig -uri $URI `
–onlyBaseResources `
-customconfig "/Person"
$allobjects | Foreach-Object {
$displayName = $_.ResourceManagementObject.ResourceManagementAttributes | `
Where-Object {$_.AttributeName -eq "DisplayName"}
if([string]::Compare($displayName.Value, "Administrator", $True) -eq 0)
{write-host "Administrator NOT deleted"}
elseif([string]::Compare($displayName.Value, "Built-in Synchronization Account", $True) -eq 0)
{write-host "Built-in Synchronization Account NOT deleted"}
else {
$objectId = (($_.ResourceManagementObject.ObjectIdentifier).split(":"))[2]
DeleteObject -objectType "Person" `
-objectId $objectId
write-host "`nObject deleted`n" $displayName.Value }

The DeleteObject function opens and closes a connection for each object.  This approach is faster:
