URGENT! I need help on LDAP - Finding deleted users Attribute "sAMAccount"

Question

Hi,
I am trying to get deleted users from Active Directory after a certain interval. Every time only the differences in the result will be shown. Also I need to get the value of the specific attribute called "sAMAccount" every time for each user(in the result).
I am using polling here.
*if (localCookie == null) {*
                    // Specify the DirSync Control
                    *Control[] ctls = new Control[] { new DirSyncControl() };*
                    ctx.setRequestControls(ctls);
               *} else {*
                    // Specify the DirSync Control with cookie
                    *Control[] ctls = { new DirSyncControl(1, Integer.MAX_VALUE, localCookie, true) };*
                    ctx.setRequestControls(ctls);
rspCtls = ctx.getResponseControls();
*if (rspCtls != null) {*
               *for (int i = 0; i < rspCtls.length; i++) {*
                    *if (rspCtls[i] instanceof DirSyncResponseControl) {*
                         *DirSyncResponseControl rspCtl = (DirSyncResponseControl) rspCtls;*
                         localCookie = rspCtl.getCookie();
The typical problem I am facing here is 2nd iteration onwards the result is not fetching the attribute "sAMAccount".
Please suggest the possible reason and solution.
