We are attempting a new install of IEM 2017.3, but can't get past the screen where we set the database connection (server, DB, credentials...). On that screen, when we test the connection if fails. We are using Windows authentication for the DB connection, rather than SQL. My DBA says the logs on the SQL server indicate that the installer is trying to connect with SQL creds, even though we specified a domain account on that screen in the installer. There is no place in the install process to select Windows authentication vs. SQL authentication.
Is there a way around this? It's hard to believe that it is unable to use Windows authentication.
