figure out what is the problem.

/**************************************************/

private System.DirectoryServices.DirectoryEntry root;

private System.DirectoryServices.DirectorySearcher ds;

private System.DirectoryServices.SearchResultCollection src;

private System.DirectoryServices.SearchResult result;

private System.DirectoryServices.DirectoryEntry user;

root = new
System.DirectoryServices.DirectoryEntry(LDAP_ROOT, LDAP_NAME,LDAP_PASS);

ds = new System.DirectoryServices.DirectorySearcher(root);

ds.set_CacheResults(true);

ds.set_Filter("(&(objectCategory=Person)(objectCla ss=user))");

src = ds.FindAll();

for(int i=0 ;i<totalRows ;i++)

{
result = (System.DirectoryServices.SearchResult) src.get_Item(i);

Well, if you do a search using DirectorySearcher, you should specify
which attributes you're interested in, so that those will be retrieved
for each of your resulting objects. This saves you from having to go
back to the full DirectoryEntry for each search result (saving you at
least one network roundtrip).

This is in C# - should be easy enough to translate into J#:

DirectorySearcher ds = new DirectorySearcher(root);
ds.Filter = "(&(objectCategory=Person)(objectClass=user))" ;

ds.PropertiesToLoad.Add("givenName");
// add any other properties you're interested in!

foreach(SearchResult oRes in ds.FindAll() )
{
Console.WriteLine(oRes.Properties["givenName"].Value);
}
