Ldap search in jsp not working

Question

Hi
We have users imported from db into oid and they have blank passwords. So for those users , when they first try to login, I am planning to take them to someother page. I have added code to login.jsp where in case of authentication error, I want to redirect users with blank password to a separate page. So I am doing a search for user in LDAP and trying to get user attributes. I am not getting any errors in my jsp , but somehow the search is not successful. Can someone tell me whats wrong with this code??
try
DirContext dirctx = null;
//Build the LDAP url
String ldapurl = "ldap://" + "stg.test.com" + ":" + "3060";
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, ldapurl);
// if password is specified, set the credentials
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL,"orcladmin");
env.put(Context.SECURITY_CREDENTIALS,"welcome");
// Bind and initialize the Directory context
dirctx = new InitialDirContext(env);
Attributes matchAttrs = new BasicAttributes(true); // ignore attribute name case
     matchAttrs.put(new BasicAttribute("uid", str_user));
     // Search for objects with those matching attributes
     NamingEnumeration answer = dirctx.search("cn=Users,dc=oprah,dc=com", matchAttrs);
     //formatResults(answer);
     int count=0;
          while (answer.hasMore()) {
               SearchResult sr = (SearchResult)answer.next();
          out.println("SEARCH RESULT:" + sr.getName());
               Attributes attrs=sr.getAttributes();
               if (attrs == null) {
                    out.println("This result has no attributes");
                    } else {
                         for (NamingEnumeration enum = attrs.getAll(); enum.hasMore();) {
                         Attribute attrib = (Attribute)enum.next();
                         out.println("ATTRIBUTE :" + attrib.getID());
                         for (NamingEnumeration e = attrib.getAll();e.hasMore();)
                              out.println("\t\t = " + e.next());
               //formatAttributes(sr.getAttributes());
          out.println("====================================================");
               count++;
          out.println("Search returned "+ count+ " results");
     dirctx.close();
catch (Exception e)
e.printStackTrace();
}

I figured the problem. I need to give the dn of orcladmin here
env.put(Context.SECURITY_PRINCIPAL,"cn=orcladmin,cn=users,dc=test,dc=com");
instead of
(Context.SECURITY_PRINCIPAL,"orcladmin");
