Wow. My company previously did an SSO implementation for our SaaS where we ran Shibboleth SP behind Apache just for SSO, with a little Python web app using mod_wsgi to call back to the main web app after SSO was completed. But for the customers that we've onboarded to SSO so far, we had to contract with a SAML expert to work with the customer to set it up. This self-service setup might be enough to make it worth our while to migrate to SSOReady.
