Fetch DN's ldap and Java

Question

Hi,
I have this ldapsearch command that I want to convert to use with Java.
ldapsearch -h HOSTNAME -p PORT -b "" -s base "(objectclass=*)" namingContexts
I want to use the ctx.search(); but I have no idea how to convert this method in to a valid search so i can get the naming contexts.
Ive tried
SearchControls searchCtls = new SearchControls();
          searchCtls.setSearchScope(SearchControls.OBJECT_SCOPE);
String searchFilter = "(objectclass=*)";
NamingEnumeration resultEnumeration =
               ctx.search("", searchFilter, searchCtls);
If there is a better way to get hold of the DN's please suggest them too me.
Thanks

I'm guessing you want to find out the distinguished names for the naming contexts held on an Active Directory Domain Controller by reading the RootDSE.
You can find some samples in the following posts:

and
http://forum.java.sun.com/thread.jspa?threadID=581470&messageID=2959885
Note that in Active Directory the RootDSE attribute called namingContexts is multivalued. The following snippet illustrates reading all of the values from the namingContexts attribute:Attribute nc = attrs.get("namingContexts");
System.out.println(nc.getID());
for (NamingEnumeration e = nc.getAll();e.hasMore();System.out.println(e.next()));
