title: How to use Certificate Authentication with the REST connector in Azure Data Factory?
body: <p>I'd like to use some of the more advanced features of the REST Dataset in Azure Data Factory (mainly pagination), but I can't see where to use Certificate Authentication.  I have an HTTP Dataset working well with Certificate Authentication, but the only options seem to be:</p>
  
  <ul>
  <li>Anonymous</li>
  <li>Basic</li>
  <li>AAD Service Principal</li>
  <li>Managed Identity</li>
  </ul>
  
  <p>Is there some way to use the AAD Service Principal or Managed Identity with a certificate?  Maybe I can do this using the Advanced settings?</p>
  
  <p>The docs say that the HTTP connector is "less functional comparing to REST connector" but this seems to be a pretty big omission from the REST version.</p>
