Client Configuration for Authentication A client might need to be manually configured to participate in the NTP Authentication Extensions detailed in this specification. On a machine that is joined to a domain, the client uses these authentication extensions to synchronize time. Applicability Statement The NTP Authentication Extensions are designed for authenticated time synchronization in domains between clients and . Clients that are joined to a domain use the NTP Authentication Extensions to synchronize time. Versioning and Capability Negotiation The NTP Authentication Extensions incorporate implicit capability negotiation based on the NTP message length, as described in sections , , and . NTP version 3, as specified in , and SNTP version 4, as specified in , apply to this extension. Vendor-Extensible Fields The NTP Authentication Extensions do not define any vendor-extensible fields. They do, however, redefine the Authenticator field of from 96 to 160 bits (per ), as described in section . Standards Assignments The NTP Authentication Extensions do not use any additional standards assignments other than the ones in the base protocols.
