title: ADFS SAML Assertion Consumer Endpoints wildcard
body: <p>I would like to know a solution to add a wildcard URL inside the SAML Assertion Consumer Endpoints. Something like that:</p>
  
  <p><a href="https://i.stack.imgur.com/dPFPo.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/dPFPo.png" alt="ADFS SAML ACS"></a></p>
  
  <p>For reviewing pull requests, each PR has its own environment with a generated URL. My goal is that each environment can use the same Relying Party Trust but I need to enter each domain for the SAML callback.</p>
  
  <p>After some research, I found this article (<a href="https://dulanja.blogspot.fr/2014/07/dissecting-saml-spec-validation-of.html" rel="nofollow noreferrer">https://dulanja.blogspot.fr/2014/07/dissecting-saml-spec-validation-of.html</a>):</p>
  
  <blockquote>
    <p>If the AssertionConsumerServiceUrl in  does not match with any of the registered ACS URLs and if the request is signed (which removes the possibility of man-in-the-middle attack), then send the response to the ACS URL in the request only if the signature is valid.</p>
  </blockquote>
  
  <p>I tried to sign my request from my SP but without success. I still have an error on the ADFS for an unregistered SAML ACS.</p>
  
  <p>Can someone has a solution for this kind of problem?</p>
  
  <p>Thanks!</p>
