Hi,
I have multi-master replication configured.

I want to replace ldap3. Please tell me how to do this ? I mean, how
does the new server synchronize the current ldap database?
You just have to deploy
your new server with an empty database (or a
database restored with a recent dump from another server, see slapcat /
slapadd). If need, adjust the olcSyncRepl line of this new host on other
hosts.
So :
- install slapd on new host
- prepare your slapd configuration (schemas, modules, databases
configurations) without syncrepl. You could rsync slapd.d directory from
another host and adjust host RID on cn=config / olcServerID. Be sure to
adjust CRC in LDIF file if you change it manually.
- restore your database with a dump from another host :
-> on ldap1 :
slapcat -n 1 > /tmp/ldif
scp /tmp/ldif ldap3:/tmp/
-> on ldap3 :
rm -f /var/lib/ldap/*
slapadd -n 1 -q -l /tmp/ldif
chown openldap: -R /var/lib/ldap/
- start slapd on ldap3
