title: WSO2 IS 5.3.0 - IWA authentication option not available
body: <p>We are using WSO2 Identity Server for user authentication.
  We have upgraded from WSO2 IS 5.2.0 version to WSO2 IS 5.3.0.
  We are using the IWA (Integrated Windows Authentication) for user authentication for our applications.</p>
  
  <p>In WSO2 5.3.0 version we do not see the option to select IWA under the Authentication Type “Local Authentication” while registering the application under “Service Provider”. This option was available in WSO2 IS 5.2.0 and we were able to use it properly.</p>
  
  <p>Can you please let us know if this feature is deprecated or disabled in the WSO2 IS 5.3.0 version? Please let us know the steps to enable IWA in WSO2 IS 5.3.0</p>
