slurpd replication problems between slave and master

[Roman Yushin <romen@infosite.ru>]

Hello. I am going to setup slurpd replication between two servers.
When i am doing changes at master, it replies to slave.(all ok!)
But when i am doing changes to slave, it don't replies to master!

Here are my configs:

So, replication between master and slave works fine.

I need that slave changes replies to master.
Are my configs wrong? Both rootdn passwords are equal.

When i am going to change slave database, connecting to the slave by 
"non-updatedn user"(for example rootdn)
no changes have been made at master and at the slave!

I am using perl-script at slave, cause standart tools doesn't work with 
updaterefs

------------------
#!/usr/bin/perl

use Net::LDAP;

$ldap = Net::LDAP->new('localhost') or die "$@";
$ldap->bind (   # bind to a directory with dn and password
             dn => 'cn=Manager,o=campus,c=ru',
           password => 'passwoooord'
                                        );

$dn="uid=user,ou=People,o=campus,c=ru";
$ldap->modify( $dn, replace => { 'cn' => 'test of perl script' });
$ldap->unbind ;
-------------------

Changes have to be done at master server by updateref link, and then 
they have to replicate by slurpd replication from master to slave, but 
it doesnt'work

Hope for your help.
