title: Not able to get new refresh token from azure AD with grant type refresh_token called with old refresh token
body: <p>I am using Azure Service management API and OAuth API for generating Access token. But while making the call for grant type "refresh_token", to refresh access token it returns new access token but that response does not has new refresh token. So I have to use old refresh token for refreshing access token. And the problem is after 5-6 hours, refreshing token returns error invalid_client(Error validating credentials. Invalid client secret is provided).
  In other cases like Office 365 app authentication via Azure AD it returns everything.</p>
  
  <p>Is there is any specific parameter or header that I have to pass with the API call ?</p>
  
  <p>Below is the screenshot of my code</p>
