Openldap Replication with Slurpd

Here I am using Master-Slave replication using Slurpd. Below are the participating systems

1. ldap-master.fireblade.com (Master Server)

2. ldap1.fireblade.com (client Server)

Replication to work properly Master and salve system initially should have exact number of entries. Take a dump of all the entries in the Master server using the below command and import it to the slave.

# slapcat > master.ldif 

Go to the salve ldap1.fireblade.com and import it using ldapadd.

#  ldapadd -D "cn=Manager,dc=dc1,dc=fireblade,dc=com" -W -x -f initial.ldif

At this point both master and slave has the exact amount of data. Let's start the replication configuration.

Open /etc/openldap/sldapd.conf in master server ldap-master.fireblade.com and add the below entries

1. Replication will happen in the every 5 minutes.

replicationinterval 300

# Keep the sapce in front of binddn as it is bbecause 
replica uri=ldap://ldap1.fireblade.com bindmethod=simple
 binddn="cn=manager,dc=fireblade,dc=com" credentials=redhat

save the configuration and exit the file.

Open /etc/openldap/sldapd.conf in the salve server ldap1.fireblade.com and add the following entries.

updatedn "cn=manager,dc=fireblade,dc=com"

updateref ldap://ldap-master.fireblade.com:389

Save the configuration and restart the ldap service in both the server and client

# service ldap restart 

Test the configuration by create a new user in the master server and test whether it appears in the slave with in 5 minutes.

Debugging
Statrt slapd and slurpd in debug mode to troubleshoot the issues

# slapd -d 1 

# slurpd -d 1
