2.2.1 PA-PK-AS-REP_OLD 1

The data for the PA-PK-AS-REP_OLD pre-authentication data identifiers is based on an earlier draft of [RFC4556]; therefore, there are some differences in the message format. The ASN.1 [ITUX680] description of the message that SHOULD<8> be used in place of the message format specified in [RFC4556] section 3.2.1 follows.

PA-PK-AS-REQ field:

  • signedAuthPack: Contains content identical to the content of the signedAuthPack field, as specified in [RFC4556] section 3.2.1.

AuthPack field:

  • pkAuthenticator: Contains a PKAuthenticator structure, as defined in this document. This variation of the AuthPack structure is different from the one specified in [RFC4556].

PKAuthenticator fields:

  • kdc-name: Contains the name portion of the ticket-granting service (TGS) name of the KDC that will service the request, as specified in [RFC4120] section 7.3.

  • kdc-realm: Contains the realm portion of the TGS name of the KDC that will service the request, as specified in [RFC4120] section 7.3.

  • cusec: Contains the same content of the corresponding, identically named field in the type PKAuthenticator, as specified in [RFC4556] section 3.2.1.

  • ctime: Contains the same content of the corresponding, identically named field in the type PKAuthenticator, as specified in [RFC4556] section 3.2.1.

  • nonce: Contains the same content of the corresponding, identically named field in the type PKAuthenticator, as specified in [RFC4556] section 3.2.1.
