Configuring AD LDS Replication If your AD LDS application requires fault tolerance
or load balancing, you can create replicas of an AD LDS instance and configure replication
between the instances. AD LDS instances containing replicas of directory partitions are referred
to as configuration sets . AD LDS instances that are part of the same configuration set must share
common configuration and schema partitions and can share common application partitions.
To create a replica of an existing AD LDS instance, you create a new instance of AD LDS
on the server to host the replica. The procedure is similar to creating a unique AD LDS instance:
1. On the server to host the new replica, click the Active Directory Lightweight Directory
Services node in Server Manager.
2. In the Advanced Tools section, start the AD LDS Setup Wizard, and then click Next.
3. In the Setup Options window, click A replica of an existing instance, and then click Next.
4. Type a name that describes the instance's purpose in the Instance Name text box, and then
click Next.
5. Type LDAP and SSL port numbers (or accept the default values), and then click Next.
6. In the Join a Configuration Set window, type the server name and the LDAP port number
for the instance you want to replicate, and then click Next.
