"updateref" doesn't work

Hi:
	I configured a slave ldap server and a master ldap server, But the 'updateref' doesn't work,
	When I insert/update/delete the data in slave ldap server, The change will go directly to slave 
	and never go to master server, Did anybody know what's happen and how to solve this issue?

	the slapd.conf in master is:

		database       	 ldbm
		suffix         	 "dc=example, dc=com"
		rootdn        	  "cn=Manager, dc=example, dc=com"

		rootpw         	 secret
		directory     	 /usr/local/var/openldap-ldbm
		replogfile 	 /usr/local/var/openldap/slapd.replog
		replica 		host=192.168.10.65:389
        				binddn="cn=Manager, dc=example, dc=com"
        				bindmethod=simple credentials=secret


	the sldap.conf in slave is:

		database        	ldbm
		suffix          	"dc=example, dc=com"
		rootdn          	"cn=Manager, dc=example, dc=com"

		rootpw          	secret
		directory       	/usr/local/var/openldap-ldbm
		updatedn 	"cn=Manager,dc=example,dc=com"
		updateref 	ldap://192.168.10.48:389

Best Regards
