We have been using the Moodle to Google Apps SSO auth plugin using SAML for several years. Today users got a security warning that the certificate wasn't trusted. We re-generated certificates because the old one was actually out of date and had the wrong server name (even though it had worked with that certificate for at least 6 months). However, now the security error says that we are using a self-signed certificate and so it isn't trusted. Google's instructions say to generate your own keys using openssl and don't mention using another certificate authority. Anyone else using this plugin still?
