Hello, i has a trouble

I'm install a ZCS 8.04 in server1 and Ldap replication in server2 follower: Configuring LDAP Replication

But when i tried in server2:
zmprov ca user@domain.com pass

User created in both server2 and server 1. This like i'm installed 2 Ldapmaster server.

I just want Ldap Replication read-only.

How to i do this? Please!
