Replication
Replication is essentially a three step process. In a nutshell,
the process is:
- The master slapd writes incoming modfications to a file
- slurpd reads the file that slapd writes to
- slurpd updates the replica servers
When slapd receives an update, it makes the modification to the LDAP
directory, then writes an LDIF version of the modification to what is
called a "replication log."
slurpd continuously monitors the replication log for changes. When
a change is made to the replication log, it reads the LDIF modification, then
updates all of the configured replica servers. The update is performed via
the LDAP protocol itself.
At this point, you should be ready to read the OpenLDAP 2.0 Administrator's Guide
