title: Lists of applications or services which allow sign on as either SAML or OpenID Connect Service Providers/Relying Parties?
body: <p>I am trying to make the case for my sector (public libraries) facilitating access to some online services for patrons by supporting either SAML or OpenID Connect as <em>identity providers</em>. The case would be much strengthened by being able to point to a list of existing 3rd party services that can integrate as Service Providers/Relying Partners using either SAML or OpenID Connect (I do realize they are different).</p>
  
  <p>So far most of my searches have turned up lists of software libraries that can provide SP/RP capabilities but no list of actual online services or applications which can support these other than this one <a href="https://apereo.github.io/cas/5.1.x/integration/Configuring-SAML-SP-Integrations.html" rel="nofollow noreferrer">https://apereo.github.io/cas/5.1.x/integration/Configuring-SAML-SP-Integrations.html</a> for SAML integrations. </p>
  
  <p>Does anyone know of other such lists that can help make the case? </p>
