Basic replication in a sysplex

A set of LDAP servers sharing a backend directory in a sysplex can act as a master, read-only, or peer server to LDAP servers that are not in the sysplex. Each LDAP server in the sysplex must have the same replication options (masterServer, masterServerDN, masterServerPW, peerServerDN, and peerServerPW) in the backend section of the LDAP server configuration file. Do not make an LDAP server in the sysplex a replica of another LDAP server in the sysplex for a backend directory that they are sharing.

When the set of LDAP servers in the sysplex is set up to be a master or a peer replica server and changes occur to the shared LDAP directory, the LDAP server acting as the owner of the sysplex group replicates the directory changes to the LDAP server replicas that are not in the sysplex. These replicas are identified by replica entries in the shared directory.

When the set of LDAP servers in the sysplex is set up to be a read-only or a peer replica server and directory changes occur to a master or peer LDAP server that is not in the sysplex, that LDAP server replicates the changes to an LDAP server in the sysplex, identified in a replica entry in the directory. The changes are made to the backend directory in the sysplex and are seen by all the LDAP servers sharing the directory in the sysplex.
