Increasing the number of records Returned in an LDAP search |
|
|
Hi,
I am try to retrieve a large (20,000) number of user objects from Active
Directory.
The DirectorySearcher object has a SizeLimit property which I have set to
100,000; but still only 1,000 records get returned.
The help for this object says that the limit is also controlled by the
server
Where (and how) on the Server can I increase the number of objects returned
in any one query of Active Directory
Thanks
Bob

Thanks Joe,
But the following code still only return 1000 items not the much larger
number I am expecting - what else do I need to do?
Thanks Again
Bob
ArrayList usrs = new ArrayList();
DirectorySearcher searcher;
SearchResultCollection results;
// Find all the users configured in the AD.
searcher = new DirectorySearcher();
searcher.SizeLimit = 1000;
searcher.Filter = "(&(objectClass=user)(objectCategory=person))";
searcher.PropertiesToLoad.Add("samaccountname");
searcher.PropertiesToLoad.Add("mail");
results = searcher.FindAll();
IEnumerator oe = results.GetEnumerator();
while (oe.MoveNext() == true)
{
usrs.Add(oe.Current);
}
MessageBox.Show(usrs.Count.ToString());

Do not modify the maxPageSize query policy on the domain controller. This
policy is in place to help protect the DC from denial of service attacks
and there is no need to change it given that paged searches are available.

Set the PageSize property to 1000. This will enabled paged results under
the hood and all results will be returned as you enumerate the search
results.

Yes - read JoeK posting and follow his advice - set the *PageSize* to
1000.

searcher.SizeLimit = 1000;
|
searcher.PageSize = 1000;
