I think Ignition does not accept windows auth for connecting to a DB, you must configure a user on your DB and enable the option to accept SQL external connections. on SQL Server it's on Server Properties \> Security \> Server authentication ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/8/18812098871dc83564270f7e4a26c7f9b2e058d7.png) another possible solution it's to upgrade your JDBC driver. ---

@paul-griffith does this still work if I am running RHEL to a MSSQL server? The documentation is all for if Ignition is running on windows correct? So what if I am running linux? ---

See [MSSQL Integrated Security on Linux Host - #4 by Kevin.Herron](https://forum.inductiveautomation.com/t/mssql-integrated-security-on-linux-host/62138/4) and [MSSQL Integrated security from a docker container - #3 by declan.mccarthy](https://forum.inductiveautomation.com/t/mssql-integrated-security-from-a-docker-container/64660/3) this isn't really documented / tested / supported by us, but it seems that at least one person has gotten it to work.
