Create a New AD LDS Instance
Applies To: Windows Server 2008
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 the AD LDS directory service. Multiple instances of the AD LDS can run simultaneously on the same computer. (This is not true for Active Directory Domain Services (AD DS).) Each instance of the AD LDS directory service has a separate directory data store, a unique service name, and a unique service description that is assigned during installation. During AD LDS installation, you have the option of creating an application directory partition if your Lightweight Directory Access Protocol (LDAP) application does not create one for you.
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 Local and Domain Default Groups (https://go.microsoft.com/fwlink/?LinkId=83477).
