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

hi there, the solution has been found now, I replace "type=refreshAndPersist" by "type=RefreshOnly" and it works.
So I now have successful ldap replication but I have new issue on secure replication. I would like to have connection between slave ldap and master ldap to be secured.
What should I do to get it work?

Here is syncrepl part of my slapd.conf file
syncrepl rid=123
provider=ldap://192.168.1.183
type=RefreshOnly
interval=00:00:00:10
searchbase="dc=weboff"
filter="(objectClass=*)"
scope=sub
attrs="*"
schemachecking=off
bindmethod=simple
binddn="cn=replicator,dc=weboff"
credentials=dfsdfjkf

updateref ldap://192.168.1.183

when the configuration is like above thing works fine. whenever I edit/add user from master ldap. It do replicate to slave ldap too.
but when I try the configuration to have secure connection like below. I couldn't have slave update anymore.

syncrepl rid=123
provider=ldaps://192.168.1.183:636
type=RefreshOnly
interval=00:00:00:10
searchbase="dc=weboff"
filter="(objectClass=*)"
scope=sub
attrs="*"
schemachecking=off
bindmethod=simple
binddn="cn=replicator,dc=weboff"
credentials=dfsdfjkf

updateref ldaps://192.168.1.183:636

Thanks
