title: Authentication issues - request.user and request.user.is_authenticated is not set
body: <ol>
  <li><p>I have a Django based application.</p>
  </li>
  <li><p>I have integrated this application with SSO (Azure AD) using the package python3-saml</p>
  </li>
  <li><p>The application URL is redirecting to Azure AD and returning the response.</p>
  </li>
  <li><p>If I check the “request.user” or “request.user.is_authenticated” there is no user details found.</p>
  </li>
  <li><p>For other applications using the plain Django configuration, the same Authentication mechanism worked fine but I have used Wagtail CMS which is causing issues.</p>
  </li>
  <li><p>If I assign “request.user” manually after successful authentication from SSO, “request.user.is_authenticated” still shows false.</p>
  <pre><code>request.user=request.session['AssocID']
  
  print(request.user) #Prints the Associate ID 
  
  print(request.user.is_authenticated) #Returns False
  </code></pre>
  </li>
  </ol>
  <p>Kindly help me obtain the details in request.user and set request.user.is_authenticated to true when authneticated.</p>
