2.2.4.1.6 ActiveDirectoryObject/ReferenceServer

When the directory service is AD DS, the ReferenceServer element is the fully qualified domain name (FQDN) (1) of the domain for this ActiveDirectoryObject, ActiveDirectoryPrincipal, or ActiveDirectoryGroup directory object. If the directory service is AD LDS, this element is a string "servername:port", where servername is the name of the AD LDS server hosting the NC for this ActiveDirectoryObject, ActiveDirectoryPrincipal, or ActiveDirectoryGroup directory object, and port is the base-10 representation of the TCP port number that the AD LDS instance is using for LDAP.
