title: java.sql.SQLException: I/O Error: SSO Failed: Native SSPI library
body: <p>I have two web-applications which need to run on Tomcat 6, MS SQL 2008 and JTDS-1.2.2 as driver.</p>
  
  <p>If I start only one web application everything is working fine, but as soon as I start the second one I get the following error (it does not matter the order):</p>
  
  <pre><code>java.sql.SQLException: I/O Error: SSO Failed: Native SSPI library
  </code></pre>
  
  <p>Of course, the library <code>ntlmauth.dll</code> is under <code>C:\WINDOWS\system32</code></p>
  
  <p>It seems that the second application which starts is not able to find the <code>ntlmauth.dll</code> for the single sign on.</p>
