Replication Overview
Unit of Replication
The smallest unit of replication is a database. This means that you can replicate an
entire database but not a subtree within a database. Therefore, when you create
your directory tree, you must take your replication plans into consideration. For
more information on how to set up your directory tree, refer to the Red Hat
Directory Server Deployment Guide.
The replication mechanism also requires that one database correspond to one
suffix. This means that you cannot replicate a suffix (or namespace) that is
distributed over two or more databases using custom distribution logic. For more
information on this topic, refer to "Creating and Maintaining Databases," on page
90.
Replication Identity
When replication occurs between two servers, the replication process uses a
special entry, often referred to as the Replication Manager entry, to identify
replication protocol exchanges. The Replication Manager entry, or any entry you
create to fulfill that role, must meet the following criteria:
•
It is created on the consumer server (or hub supplier) and not on the supplier
server.
•
You must create this entry on every server that receives updates from another
server, meaning on every hub supplier or dedicated consumer.
•
When you configure a replica that receives updates from another server, you
must specify this entry as the one authorized to perform replication updates.
•
When you configure the replication agreement on the supplier server, you
must specify the DN of this entry in the replication agreement.
•
This entry must not be part of the replicated database for security reasons.
•
This entry, with its special user profile, bypasses all access control rules
defined on the consumer server.

In the Directory Server Console, this Replication Manager entry is
referred to as the supplier bind DN, which may be misleading as the
entry does not actually exist on the supplier server. It is called the
supplier bind DN because it is the entry which must be present on
the consumer for the supplier to be able to bind to the consumer.
