You use the Active Directory Lightweight Directory Services Setup Wizard to create Active Directory Lightweight Directory Services (AD LDS) service instances. In AD LDS, a "service instance" (or, simply, "instance") refers to a single running copy of AD LDS. To provide fault tolerance and load balancing, AD LDS instances can be part of a configuration set. All AD LDS instances in a configuration set replicate a common configuration directory partition and a common schema directory partition, plus any number of application directory partitions.

To create an AD LDS instance and join it to an existing configuration set, use the Active Directory Lightweight Directory Services Set Wizard to create a replica AD LDS instance. You need to know the Domain Name System (DNS) name of the server running an AD LDS instance that belongs to the configuration set, as well as the Lightweight Directory Access Protocol (LDAP) port that was specified when the instance was created. You can also supply the distinguished names (also known as DNs) of specific application directory partitions that you want to copy from the configuration set to the AD LDS instance that you are creating.

Membership in the Administrators group, or equivalent, is the minimum required to complete this procedure. Review details about using the appropriate accounts and group memberships at https://go.microsoft.com/fwlink/?LinkId=83477.
