title: Custom attributes are missing in HTTP Request Header, But it is present in Shibboleth response
body: <p>1) We have created a Custom attribute map(Custom-attribute-map.xml) and placed the file in the shibboleth folder.</p>
  
  <pre><code>eg : 
      &lt;Attribute name="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress" id="emailaddress"/&gt;
  </code></pre>
  
  <p>2 )Then we set the path in shibboleth2.xml</p>
  
  <pre><code>&lt;AttributeExtractor type="XML" validate="true" reloadChanges="false" path="Custom-attribute-map.xml"/&gt;
  </code></pre>
  
  <p>So we will get those custom headers in my Application request that comes from Shibboleth .<strong>This is working fine for 2 out of 3 server</strong>. </p>
  
  <p>We have done the same procedure in the 3rd server also but the <strong>custom headers are missing</strong> in 3rd server's <strong>application Request header</strong> (Request.Headers["emailaddress"])</p>
  
  <p>We have checked Shibboleth log, There those custom attributes are available.</p>
  
  <pre><code> &lt;Attribute Name="http://schemas.xmlsoap.org/ws/2005/05/identity/claims/emailaddress"&gt;
                  &lt;AttributeValue&gt;UserName@Company.com&lt;/AttributeValue&gt;
              &lt;/Attribute&gt;
  </code></pre>
  
  <p>But those custom headers are not adding into the request header</p>
  
  <p>what can be the reason for this problem?</p>
