I have a problemwith LDAP. I would like to modify couple of attributes but it doesn’t work. With cursor().get().put(attr, value) the value is modified only local and if I check if that changed attribute was changed on server side, the old value remains untouched.

How can I send modified value, so it will we saved in database?

{
    LdapConnectionConfig config = new LdapConnectionConfig();
    config.setUseSsl(true);
    config.setLdapHost(server);
    config.setLdapPort(port);
    config.setName(
        "cn=%s,DC=xyz,DC=local".formatted(user)
    );
    config.setCredentials(password);
    config.setTrustManagers(new X() {
        public boolean isClientTrusted(someMethod[] cert) { some auth code
    });

    try(LdapConnection conn = new LdapNetworkConnection(config)) {            
        conn.connect();
        conn.bind();
        SearchRequestImpl queryRequest = new SearchRequestImpl();
        queryRequest.setScope(SearchScope.SUBTREE);
        
     
        EntryCursor cursor = conn.search(base, query, SearchScope.SUBTREE);
        String queryResult = "";
        if(cursor.next()) {
         
            System.out.println("cursor before:<<<<<<<<<<<<<<<<<<<< " + cursor.get().toString());
            cursor.get().removeAttributes("xxx");
            cursor.get().put("xxx", "111");
            System.out.println("cursor after:<<<<<<<<<<<<<<<<<<<< " + cursor.get().toString());
            queryResult += cursor.get().toString();

        }
        
        conn.unBind();

    } catch(IOException  e) {
        throw new RuntimeException(e.getMessage());
    } 
}
