LinuxQuestions.org - ldap replication

Hi all this is my slapd.conf file. My problem is that I can make it replicate (I 've checked in phpldapadmin all group and user were copied in slave ldap from master by syncrepl)
but after I add more user on master ldap, I didn't see the user I add in slave ldap so I add interval into slapd.conf like I paste here (which I am not sure what it mean, may every hour)<=if anyone know please explain Till now I am really not sure if it can update or not.
How can I check this? thanks
