Resyncing basic question..

Hello, I’m wondering about the correct way to resync a directory in a push configuration… The setup is the following (as described in the documentation) : - on the master I have added a second suffix with the hidden property and the same suffix value. - this suffix have an ldap backend on another computer which is the real slave. I know the procedure to resynchronize two directory when the slave is in a pull configuration : get the csn of the master and restart the slave with the csn as argument. But in the push configuration : do I need to restart the slave (the backend of the second suffix ) ? Or the master which deals with the hidden suffix ? I hope my explanation are clear. Thanks in advance. f.g.
