title: How the logoutRequests in SAML are signed?
body: <p>I'm trying to integrate one Identity Provider in one application we have in PHP. The middleware I'm using in PHP is SamlTool from OneLogin<a href="https://www.samltool.com/" rel="nofollow" title="Saml Tool from One Login official site">1</a>. </p>
  
  <p>However, when I try to sign the logout Request, that is not working. </p>
  
  <p>I notice that If I try to sign the request and then I check signature they create in their site, is different.</p>
  
  <p>So the question is how is the signature for Saml Logout Request signed.</p>
