Non-local users without a local password entry could not print to unauthenticated queues after the CVE-2026-27447 fix. This patch adds a fallback for case-insensitive username comparison when the user has no local password entry and auth type is CUPSD_AUTH_NONE. Origin: upstream, OpenPrinting/cups@849fba7d7a
