Hi i install openldap in servers and create replica but is not runin perfectly

My entry in ldap server:

MASTER SERVER:

replogfile /var/log/replica/replica.log replica host=hostname_slave.domain.com:389 binddn="cn=Administrator,dc=domain,dc=com" bindmethod=simple credentials=123456 tls=none

################################################## ######################

SLAVE SERVER: updatedn "cn=Administrator,dc=domain,dc=com" updateref ldap://hostname_master.domain.com

In my /etc/hosts configure any hostnames...

The file replica.log is empty and not create replica.

I execute normaly /etc/init.d/slurpd start only master server.

Is necessary running slurod daemon is slave server? Exist other configuration to slapd.conf?

My slapd.conf is same in master and slave except lines reference the replica.

Thanks for your helps.....

Best
