Good morning. I have several Django apps running in my work environment. All are running through Gunicorn on Ubuntu. I have a new app that must run on Windows for ODBC reasons. This new app is running in development mode on a Windows 10 PC. I run the dev server while logged in as a service account, it uses a trusted connection (local credentials as I understand) to query a SQL server and works perfectly. I ported this app (virtualenv and all) to a Windows Server 2012 r2 instance and run the dev server successfully from there using my domain admin credentials (again trusted_connection=yes).
I set up IIS on this server to run the app permanently and it appears to run. However, I get a django error page that says the SQL login failed for 'DOMAINNAME\SERVERNAME'. I have tried editing my Application Pool to use the credentials of the working service account (Advanced Settings > Process Model > Identity). With this configuration I no longer see a Django error page, just Service Unavailable HTTP Error 503. I have tried 'recycling' and restarting the IIS service after the change but that has not worked.
Unfortunately, I do not have admin access to the SQL server to create or edit accounts. Is it possible to configure IIS to connect to SQL, through the app, using the service account credentials that I know work. If I were to configure the Application Pool successfully in this way should I still have the trusted connection setting in my connection string? Thanks!
