title: Suborganizations and Unique id
body: <p>I can succesfully authenticate my application with ApacheDS</p>
  
  <p>But now i use only one domain.</p>
  
  <p>I want to add subdomains or sub organizations under root domain.</p>
  
  <p>For example a root organization as </p>
  
  <pre><code>dc=example,dc=com
  </code></pre>
  
  <p>and sub organizations <code>dc=x</code></p>
  
  <p>another sub organization <code>dc=y</code></p>
  
  <p>Now i can authenticate users using uid attribute</p>
  
  <p>like:</p>
  
  <pre><code>user-search-filter="(uid={0})"
  </code></pre>
  
  <p>i use login name like user1, without an @ extension</p>
  
  <p>But i want to have suborganizations and i want to use user1@x.example.com</p>
  
  <p>Is it possible and how?</p>
  
  <p>My application is a spring application but i think subject is independent from my application side.</p>
