What is LDAP syncrepl?

The LDAP Sync replication engine, syncrepl for short, is a consumer-side replication engine that enables the consumer LDAP server to maintain a shadow copy of a DIT fragment. A syncrepl engine resides at the consumer-side as one of the slapd (8) threads.

How does syncrepl manage replicas?

Syncrepl also enables convenient management of replicas by maintaining replica status. The consumer replica can be constructed from a consumer-side or a provider-side backup at any synchronization status. Syncrepl can automatically resynchronize the consumer replica up-to-date with the current provider content.

Where can I find the syncrepl specification?

Because syncrepl is a consumer-side replication engine, the syncrepl specification is defined in slapd.conf(5) of the consumer server, not in the provider server’s configuration file.

How does SLAPD(8) work with syncrepl?

If a syncrepl specification is included in a database definition, slapd(8) launches a syncrepl engine as a slapd(8) thread and schedules its execution. If the refreshOnlyoperation is specified, the syncrepl engine will be rescheduled at the interval time after a synchronization operation is completed.
