Connecting to MS SQL Server using Windows authentication and JTDS

Question

I am unable to connect to SQL Server using Windows Authentification. This is is the exception being thrown:

Caused by: java.io.IOException: SSO Failed: Native SSPI library not loaded. Check the java.library.path system property.
    at net.sourceforge.jtds.jdbc.TdsCore.sendMSLoginPkt(TdsCore.java:1889)
    at net.sourceforge.jtds.jdbc.TdsCore.login(TdsCore.java:587)
    ... 35 more

Here is the Spring configuration:

@Bean
  public DataSource dataSource() {
    BasicDataSource dataSource = new BasicDataSource();
    dataSource.setDriverClassName("net.sourceforge.jtds.jdbc.Driver");
    dataSource.setUrl(...);
    return dataSource;
  }

The following VM argument is defined:

-Djava.library.path=C:\x64\SSO

This points to ntlmauth.dll (from jtds-1.3.1-dist.zip)

The following dependency is defined in the pom:

<dependency>
   <groupId>net.sourceforge.jtds</groupId>
   <artifactId>com.springsource.net.sourceforge.jtds</artifactId>
   <version>1.2.2</version>
</dependency>

Have obviously omitted something - any help is very appreciated!
