Hi Cordialement, Thanks for your reply. At present I am using below code for performing persistent search. LdapConnection connection = new LdapConnection("localhost", 389); connection.bind("CN=Administrator,cn=users,dc=example,dc=com", "password123"); Control psearchControl = new PersistentSearchControl(); SearchRequest sr = new SearchRequest(); sr.setBaseDn("dc=orademo,dc=com"); sr.setFilter("(objectclass=*)"); sr.setScope(SearchScope.SUBTREE); sr.add(psearchControl); SearchCursor results = (SearchCursor) connection.search(sr); I need to perform this persistent search operation on Active Directory . For Active Directory OID for persistent search is 1.2.840.113556.1.4.528 which is diffrent from standard oid 2.16.840.1.113730.3.4. So how can i change defined PersistentSearchControl OId to this new OID.
