As part of our current project we needed to recreate User Profile Application (UPA). Here is the PowerShell script in case you need to find the current configuration of User Properties under Manage Profile Service.

 # Load the SharePoint PowerShell snapin if needed

    Add-PSSnapin Microsoft.SharePoint.PowerShell

#Start the document and add the root node
$writer.WriteStartDocument();

foreach ($item in $properties)
{
    #Create the property element
    $writer.WriteStartElement("property");

    #Look up any AD mappings in the PropertyManagerCollection and include them
    $writer.WriteAttributeString("IsImport",$pmc.Item($item.Name).IsImport);

    $writer.WriteEndElement();

}

#Finish up
$writer.WriteEndElement();
$writer.WriteEndDocument();
$writer.Flush(); 
$writer.Close();

#Capture the output into a string
$result=$sw.ToString();

# Write the XML out
#Write-Output $result;

$result | out-file $OutputFile -force

The next step will be creating/updating User Properties under Manage Profile Service based on the XML file produced by this script.

That was another page in the Chronicles of SharePoint Bits, happy scripting!
