As we have seen pymssql not being developed for a while due to Microsoft open sourcing these tools we can now use this Dockerfile to have native MS SQL Client support in Linux. This describes Ubuntu (Specifically 16.04) but can very easily be changed.

There are several environment variables you optionally can set up to store secure information about your MSSQL connection. Set the following as Domino environment variables on your user account:
DB_SERVER DB_USERNAME DB_PASSWORD

Have a powerful day!
