title: DB2 connection without specifying username and password
body: <p>I have installed <code>DB2 Express C 9.7.4</code> edition.</p>
  
  <p>I am establishing <code>DB2 Connection</code> using <code>JAVA language</code>.</p>
  
  <p>But I have to still provide <code>user name and password of my windows Login</code> account for establishing connection...</p>
  
  <p>Is it necessary to mention it ?</p>
  
  <p>Is there any way out that can establish connection without specifying user name/password as during installation we have skipped the page.</p>
  
  <p>Thanks in advance...</p>
