In certain situations, the Kerberos [RFC4120] client may wish to authenticate a server and/or protect communications without revealing the client's own identity. For example, consider an application that provides read access to a research database and that permits queries by arbitrary requesters. A client of such a service might wish to authenticate the service, to establish trust in the information received from it, but might not wish to disclose the client's identity to the service for privacy reasons.

                      Anonymity Support for Kerberos


   This document defines extensions to the Kerberos protocol to allow a    Kerberos client to securely communicate with a Kerberos application    service without revealing its identity, or without revealing more    than its Kerberos realm.  It also defines extensions that allow a    Kerberos client to obtain anonymous credentials without revealing its    identity to the Kerberos Key Distribution Center (KDC).  This    document updates RFCs 4120, 4121, and 4556.  This document obsoletes    RFC 6112 and reclassifies that document as Historic.  RFC 6112    contained errors, and the protocol described in that specification is    not interoperable with any known implementation.  This specification    describes a protocol that interoperates with multiple    implementations.
