Problem with MS SQL Windows authentication on a linux container

In preparation of hosting Teamcity on AKS (Kubernetes on Azure), i'm running it locally in a Linux docker container. I'm using the official Jetbrains container from the Docker hub, version: 2018.2.4-linux. I have it up and running on a Windows 10 testmachine using a MS SQL database on the designated MS SQL server. The data and logs folders are mapped to a local folder on the test machine. Now i'm trying to make the step to Windows authentication. I followed the instructions on this page https://confluence.jetbrains.com/display/TCD18/Setting+up+TeamCity+with+MS+SQL+Server#SettingupTeamCitywithMSSQLServer-integratedSecurityAuth, but i'm having a problem getting it to work. The manual asks me to put sqljdbc_auth.dll in %data%\lib\jdbc\native\windows-amd64\, but it is a Linux container so a dll will not work (tried it, error message is below). The error mentiones a libsqljdbc_auth.so, but i cant find any documentation about this.

This is the error i get during configuring in the webinterface:
Could not connect to the database: no sqljdbc_auth in java.library.path. To make the native part of the driver available, you can place libsqljdbc_auth.so into the '/data/teamcity_server/datadir/lib/jdbc/native/linux-amd64' directory.

In the server log i get this error:
