Provider fails

Hi

I am planning to implement sync replication for ldap replication
purposes. But the problem is that when I add the following entries to
slapd.conf and restart ldap

overlay syncprov
syncprov-checkpoint 1 10
syncprov-sessionlog 1000

I get

[19:37:28] root@b5c4m4p215.srTachyon.com - ~> /etc/init.d/ldap restart
Stopping slapd:                                            [  OK  ]
Checking configuration files for slapd: slaptest: bad configuration file!
                                                                       
[FAILED]

Any idea what is wrong with me?  Shall set up consumer before restarting
slapd on provider?

Thanks
Sadique
