VertiGIS Studio Workflow configuration instruction

Hi All,

I have vertigis studio workflow installation in web server with windows authentication + anonymous authentication, Application pool is using the buildin apppool identity. Portal for ArcGIS is using the windows authentication as well. We have install the https://github.com/vertigis/arcgis-web-adaptor-extensions this extension also. So far working with Windows Authentication. We want to set the sql server database access permission so we change the application pool account with AD user. And then we can no longer login to workflow designer throught portal. It is happening at the portal side. Do we need to add that application service user account into the portal with service account and give the permission?
