title: ADFS SAML request is not signed with expected signature algorithm
body: <p>ADFS has unexpected behavior that looks like a bug.</p>
  
  <p>I have SP that is using SHA1 hash algorithm for digital signing.
  On ADFS for this SP I set on advanced tab to use SHA256.</p>
  
  <p>For me it is normal that these are not in correlation each side choose how will sign. </p>
  
  <p>When I did sign out from SP I did signing with SHA1. On ADFS I got exception :</p>
  
  <pre><code>SAML request is not signed with expected signature algorithm. SAML request is signed with signature algorithm http://www.w3.org/2001/04/xmldsig-more#rsa-sha256 . Expected signature algorithm is http://www.w3.org/2000/09/xmldsig#rsa-sha1 
  </code></pre>
  
  <p>I am using ADFS 3 , Windows R2</p>
