title: No MetadataProvider available - shibsp::ConfigurationException
body: <p>I recently upgraded Shibboleth  from versionShibboleth-sp-2.5.6.0-win64 to Shibboleth-sp-2.6.0.0-win64 and Apache web server from 2.4.16 to 2.4.23.</p>
  
  <p>Post the upgrade, when I try to access my application I get the following error:</p>
  
  <pre><code>shibsp::ConfigurationException
  
  The system encountered an error at Fri Oct 14 20:19:51 2016
  
  To report this problem, please contact the site administrator at root@localhost. 
  
  Please include the following message in any email:

  No MetadataProvider available.
  </code></pre>
  
  <p>When I access, https:/xxxxx.xxxxx/Shibboleth.sso/Metadata, the metadata file is downloaded and the details seems correct. </p>
  
  <p>Does any one know why does this error occur and how can we solve it?</p>
