title: search by samaccountname with wildcards
body: <p>I have this code:</p>
  
  <pre><code> public static DataTable ExecutesAMAccountNameQuery(string sAMAccountName)
          {
              string filter = "(&amp;(objectCategory=person)(objectClass=user)(sAMAccountName=" + sAMAccountName + "))";
              return ExecuteADQuery("GC:", filter);
          }
  </code></pre>
  
  <p>It only works with the full username, I dont know the syntax to make it work with wildcards, like a LIKE in sql?</p>
  
  <p>Thanks</p>
