The master replica is a writable replica type used to initiate changes to an object or [NDS Partition]. The [{$pagename}] manages the following types of [NDS Partition] operations:
* Adding replicas to [NcpServer]
* Removing replicas from [NcpServer]
* Creating new partitions in the [eDirectory] tree
* Removing existing [NDS Partitions] from the [eDirectory] tree
* Relocating a [NDS Partitions] in the [eDirectory] tree

The [{$pagename}] is also used to perform the following types of [eDirectory] object operations:
* Adding new [LDAP Entry] to the [eDirectory] tree
* Removing, renaming, or relocating existing a [LDAP Entry] in the [eDirectory] tree
* Authenticating objects to the [eDirectory] tree
* Adding new object [LDAP Schema] items to the [eDirectory] tree 
* Modifying or removing existing [LDAP Schema] items.

By default, the first [eDirectory] server on your network becomes [{$pagename}]. There is only one [{$pagename}] for each partition at a time. If other replicas are created, they are read/write replicas by default.

If you're going to bring down the server holding a [{$pagename}] for longer than a day or two, you can make one of the read/write replicas the master. The original master replica automatically becomes read/write.

A master replica [MUST] be available on the network for [eDirectory] to perform operations such as creating a new [replica] or creating a new [NDS Partition].

Do __NOT__ confuse [eDirectory] [{$pagename}] with [LDAP] [Multi-master replication]. All Edirectory and Read/Write Replica servers are [LDAP] [Multi-master] Servers.
