Setup two OpenLDAP servers, one Master, one Slave, so when an entry in one of the servers is changed it is automatically changed in the other server. This is handy so you can distribute the load between the two servers, use one of the servers for one set of programs and use the other server for a different set of programs.

1. Copy the ldap.conf & slapd.conf files into the '/etc/openldap/' directory approperate Master/Slave servers & start the openldap servers.
/etc/init.d/ldap start
2. Make the following domain file domain.ldif
nano /tmp/domain.ldif
| dn: dc=fedora,dc=directory,dc=server objectclass: dcobject objectClass: organization o: Fedora Directory Server dc: Fedora |
3. Run the following command on the master server to add root directory of the LDAP tree
ldapadd -x -D cn=Manager,dc=fedora,dc=directory,dc=server -W -f /tmp/domain.ldif -h localhost
4. After you have setup your master OpenLDAP server then export the ldif file and copy it over to the slave server.
slapcat -l /tmp/master.ldif
5. Change to the OpenLDAP slave server, now add the master.ldif file to the slave OpenLDAP server.
ldapadd -x -D cn=Manager,dc=fedora,dc=directory,dc=server -W -f /tmp/master.ldif -h localhost
6. Now start the both the Master/Slave servers.
slave server: /etc/init.d/ldap start
master server: /etc/init.d/ldap start
I suggest you try and install a LDAP gui and test it out by adding and deleting LDAP entries.
