Problem with SearchControls object with regards to LDAP

[thelordoftherings]

Hello,

I am using a SearchControls object in order to search in my LDAP.
I would like to get our departments inside the organization. For that I need only the OUs without the users inside them. The problem is this:
Assume controls is of type SearchControls.
When I use:
controls.setSearchScope(SearchControls.SUBTREE_SCOPE);
I receive a list with the whole users but when I use:
controls.setSearchScope(SearchControls.ONELEVEL_SCOPE);
I receive nothing.
Why is that and how do I solve it?

10X Dian, I am familiar with these arcticles.
The problem is that SUBTREE_SCOPE Starts at the base entry; searches the base entry and everything below it. This is not good for me since it will bring the whole users inside the OU which I don't need and is very heavy.
On the other hand, ONELEVEL_SCOPE Searches only the entries below the base entry. This is not good as well since I won't get nested OU's...

What I need is the information just about my OU's, not the users inside them. I need this to get a list of all the departments in our organization and if inside OU A there are 200 users + another OU B which has 200 users inside it as well, all I need from the results is to retreive me OU A and OU B from them I will fetch the necessary data.
