It works fixing /src/Spid/Saml/Idp.php from
$metadata['idpCertValue'] = self::formatCert($xml->xpath('//ds:X509Certificate')[0]->__toString());
to
$metadata['idpCertValue'] = self::formatCert($xml->xpath('//md:IDPSSODescriptor//ds:X509Certificate')[0]->__toString());

Occhio che poi non funziona con LEPIDA, meglio un condizionale
