KB-1410 Is Integrated Security Windows authentication with SQL Server possible in Appian Cloud?

Integrated Windows authentication with a Microsoft SQL Server database is not supported in Appian Cloud. It requires the party making the request to be running as a Windows account or to use an open source driver, neither of which are supported in Appian Cloud.

To test connectivity to the Microsoft SQL Server database, you will need to enable username/password authentication (SQL Server authentication) on the database side and test connectivity with those credentials.
