I recently set up a dev environment on a new workstation, and did not get my private key copied into the location specified in the SP settings form. This dumps an error to the browser:
OneLogin\Saml2\Error: Invalid array settings: sp_certs_not_found_and_required in OneLogin\Saml2\Settings->__construct() (line 141 of /app/vendor/onelogin/php-saml/src/Saml2/Settings.php.
After saving the settings form, move your cert or private key out of the location specified.
Attached MR presents a friendlier message (“Configuration error: login is unavailable.”) to the user and redirects them to <front>. It logs the actual exception.
Possibly add a check to the “Status report” page by implementing hook_requirements()? I doubt this happens with enough frequency to make that worthwhile, though we could also consider adding a warning for the cert expiring soon (or an error that it has expired).
