title: Service providers with SAML version 2 for SSO accessible to public?
body: <p>I'm wondering if there are any publicly available SAML version 2 SPs (Service Providers) that can be used to test SSO(Single Sign On)</p>
  <p>Salesforce and Google apps both have an SSO solution, but how to go get access to them and what is the cost for those services?</p>
  <p>I could setup a service provider using <a href="http://opensso.sourceforge.net/" rel="nofollow noreferrer">OpenSSO</a> on an another system for my testing purpose.</p>
