Importing LDAP data from master to replica

Article Information
This article applies to the following ZCS versions.

ZCS 5.0 Article ZCS 5.0

If an ldap replica is not in sync with the master, it is possible to manually load all of the data from the master into the replica.

On the ZCS node where the ldap master is running

Export an ldif of the master ldap database.

# su - zimbra
$ ldap stop
$ ~/openldap/sbin/slapcat -b "" -f ~/conf/slapd.conf -l /tmp/ldap-master.ldif
$ ldap start

On the ZCS node where the ldap replica is running

Copy the file ldap-master.ldif from the master to the replica (this example assumes that the hostname of the master is

# su - zimbra
$ scp /tmp/

Stop the ldap service.

$ ldap stop

As root, move aside the existing ldap data (for this example, the data directory is renamed with the current date (2007-12-07) and state (out-of-sync) of the data), and create a new empty data directory. Consult the LDAP section of the performance tuning guide for tips on configuring the DB_CONFIG file if necessary.

$ exit
# mv /opt/zimbra/openldap-data /opt/zimbra/openldap-data.2007-12-07-out-of-sync
# mkdir -p /opt/zimbra/openldap-data/logs
# cp /opt/zimbra/openldap-data.2007-12-07-out-of-sync/DB_CONFIG /opt/zimbra/openldap-data/
# chown -R zimbra:zimbra /opt/zimbra/openldap-data

As the zimbra user, import the ldap master data. This may take minutes (or even hours), depending on the amount of data and the settings in DB_CONFIG.

# su - zimbra
$ ~/openldap/sbin/slapadd -b "" -q -f ~/conf/slapd.conf -l /tmp/ldap-master.ldif

Then start the ldap service and run a test query.

$ ldap start
$ zmprov --ldap getAllServers
