LDAP Search returns only 1200 records

Question

Hi!
I'm having trouble searching an LDAP registry containing about 20 000 records. If I configure a search that should return about 15000 records I only get 1200 with the following error message when iterating through the NamingEnumeration:
Unexpected exception occured at record 1200: javax.naming.SizeLimitExceededExcep
tion: [LDAP: error code 4 - Sizelimit Exceeded]; remaining name 'o=ericsson'
Code:
package erildap;
import javax.naming.*;
import javax.naming.directory.*;
import java.util.Hashtable;

Hi,
Two possible reasons:
1. The size of the search results returned would have been controlled by the directory services administrator (Cross- check with the dir. services administrative options.
2. Have you set the size limit programatically... using SearchControls.setSizeLimit(...) you should be using
SearchControls.setSizeLimit(0) which returns all the results.
Hope this hleps,
