I don't understand why "no sqljdbc_auth in java.library.path" persists

I am trying to connect a java program to an SQL Server database.

The important is that I am working on a Windows 7 machine, my Eclipse is on a Linux machine on my company's network, and the SQL Server requests a Windows authentication.

I copied and pasted the driver sqljdbc41.jar in the location of my project (on Eclipse right click on the project, properties and see location). I also pasted the sqljdbc_auth.dll in the same location. I have tried to add the path to this .dll on the "Native Library location following this post : https://stackoverflow.com/a/958074/7812989 . But I still have this error :

My code is the following : 

    package sqlconnectiontest;

    import java.sql.*;

    public class SqlSelection {

        /**
         * @param args
         */
        public static void main(String[] args) {
            try
            {
                Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

                String userName = "myUser";
                String password = "myPassword";
                String url = "jdbc:sqlserver://fr0-iaascls-190.eu.company.corp:10001;databaseName=MYDATABASE;integratedSecurity=true;";
                Connection con = DriverManager.getConnection(url, userName, password);    
            } 
            catch (Exception e)
            {
                e.printStackTrace();
            }

        }
    }

Do you have an idea that may help please ? Thank you :)

You may get this error message if the application is trying to use the incorrect architecture (x86 VS x64) version of the sqljdbc_auth.dll. Try specifying the directory path to the other architecture.

If you are on a x64 machine running x64 OS, but the JVM you are using is the x86 version, you will need to specify and use the x86 version of the sqljdbc_auth.dll.
