Currently, you can only authenticate a patron by Patron ID or Barcode . Sometimes the libraries in the consortia don't tell us their barcode prefixes have changed and patrons were being blocked for no reason. So we are utilizing the SIP connection with OverDrive and Kanopy to block against patron type in Polaris, no longer utilizing the barcode prefixes so patrons have easier access. Now that fix might not work in Vega to authenticate OverDrive because we don't use the barcode.
