How to Use PowerShell to Fix an ObjectSID on an FIM Portal Object

How to Use PowerShell to Fix an ObjectSID on an FIM Portal Object

FIM ScriptBox Item

Summary

Sometimes the ObjectSID just isn't what you want it to be or it's been unintentionally recalled due to another action. :)
This script should fix the portal object, just pass it the account name and domain on the command line and it will retrieve the SID, find the object by AccountName in the portal and then fix it if it is wrong.
