2.276 Attribute sPNMappings

  • [アーティクル]

This multivalued attribute contains a list of service principal names (SPNs) to show the equivalence of SPN types. The SPN is the name a client uses to uniquely identify an instance of a service. If an implementer installs multiple instances of a service on computers throughout a forest, each instance has to have its own SPN. A given service instance can have multiple SPNs if there are multiple names that clients might use for authentication. For example, "ldap/..." SPNs could be mapped so that they are equivalent to "host/..." SPNs. For more information on Active Directory usage, refer to [MS-DRSR] section 4.1.4.2.19.
