If you start your application in a browser, be sure to map:

<servlet>
  <servlet-name>NtlmHandler</servlet-name>
  <display-name>Servlet based ntlm authentication</display-name>
  <servlet-class>com.sibvisions.apps.server.http.NtlmHandler</servlet-class>
</servlet>
 
<servlet-mapping>
  <servlet-name>NtlmHandler</servlet-name>
  <url-pattern>/auth/Ntlm</url-pattern>
</servlet-mapping>

in your web.xml.

The authentication was successfully tested with WinXP, Vista, Win7, Win8 - Java5, 6, 7. It's not needed to change your local security policies because NTLMv1 and NTLMv2 work.
