Configuring LDAP Replication Setting up LDAP replication lets you distribute Zimbra server queries to specific replica LDAP servers. Only one master LDAP server can be set up. This server is authoritative for user information, server configuration, etc. Replica LDAP servers can be defined to improve performance and to reduce the load on the master server. All updates are made to the master server and these updates are copied to the replica servers. The Zimbra install program is used to configure a master LDAP server and additional read-only replica LDAP servers. The master LDAP server is installed and configured first, following the normal ZCS installation options. The LDAP replica server installation is modified to point the replica server to the LDAP master host. When the master LDAP server and the replica LDAP servers are correctly installed, the following is automatically configured: SSH keys are set up on each LDAP server Trusted authentication between the master LDAP and the LDAP replica servers is set up The content of the master LDAP directory is copied to the replica LDAP server. Replica LDAP servers are read-only. Zimbra servers are configured to query the replica LDAP server instead of the master LDAP server.
