If you see such issue after installing Shetab SharePoint Live Authentication just perform IISRESET and try again.
If you have "alternative mapping address" for a SharePoint site, do following steps
  1. Edit "Vars.bat" in Shetab SharePoint Live Authentication Configure folder.
  2. Set url parameter to your new mapping address of your SharePoint site.
  3. Run "add.bat".
  4. IISRESET (not required for version 4.1 and upper).
