sync_(client|server) problem

Hi, list
I'm trying to make master-master rolling replication with
sync_(client|server) on two cyrus imapd servers. It's working, but
only when I run sync_client process manually, after cyrus is starting.
When I run it from cyrus.conf START section (as recommended
http://cyrusimap.web.cmu.edu/imapd/install-replication.html) only two
processes start -- idled and sync_client.
Both servers are using ldap database for user accounts and possibly
the problem is in ptloader -- it might not be started before
sync_client. Option -w, for sync_client also, doesn't resolve this
problem.
Can somebody help me?
