title: If I send an Authnrequest to simpleSAMLphp (as IDP), what is the corrct URL to send it to?
body: <p>I want to sent an AuthnRequest from my python-based SP (I;m using python 2.7) that I'm developing to my simpleSAMLphp installation (it's an IDP).</p>
  <p>I'm using the &quot;requests&quot; module to do a get like this:</p>
  <p>response = requests.get(url, verify='/home/barrie/my.crt')</p>
  <p>where the URL is:</p>
  <p><a href="https://bingo.bas.com/simplesaml/module.php/core/authenticate.php?as=example-sql/?SAMLRequest=%27" rel="nofollow noreferrer">https://bingo.bas.com/simplesaml/module.php/core/authenticate.php?as=example-sql/?SAMLRequest='</a> + saml_request_base64</p>
  <p>and the saml_request is (but converted to base64):</p>
  <pre><code>    &lt;samlp:AuthnRequest\
        xmlns:samlp=&quot;urn:oasis:names:tc:SAML:2.0:protocol&quot;\
        AssertionConsumerServiceURL=&quot;http://localhost:8081/&quot;\
        Destination=&quot;https://bingo.bas.com&quot;\
        ID=&quot;asdfasdfasdfasdf&quot;\
        IssueInstant=&quot;2020-08-05T16:37:18.517845+00:00&quot;\
        ProtocolBinding=&quot;urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST\
        Version=&quot;2.0&quot;\
        &lt;saml:Issuer xmlns:saml=&quot;urn:oasis:names:tc:SAML:2.0:assertion&quot;&gt;https://localhost:8081/&lt;/saml:Issuer&gt;\
      &lt;/samlp:AuthnRequest&gt;'
  </code></pre>
  <p>Is this the right way to go about it or is there a better (or correct) way?</p>
