3.2.2.6.2.1.4.5.9 msPKI-Certificate-Name-Flag

  • [アーティクル]

The following processing rules are applied to flags in this attribute. If the CA fails to obtain any data that is required by this section to be stored in the certificate, the CA MUST return a nonzero error to the client.

  1. The CA MUST ignore the CT_FLAG_ENROLLEE_SUPPLIES_SUBJECT_ALT_NAME flag.

  2. If the CT_FLAG_ENROLLEE_SUPPLIES_SUBJECT flag is not set, then:

    1. The CA MUST ignore any subject name information provided in the certificate request.

    2. If the CT_FLAG_SUBJECT_REQUIRE_DIRECTORY_PATH flag is set, then the CA MUST set the Subject field of the issued certificate to the requestor's DN from the working directory

    3. If the CT_FLAG_SUBJECT_REQUIRE_DIRECTORY_PATH flag is not set and either the CT_FLAG_SUBJECT_REQUIRE_COMMON_NAME or CT_FLAG_SUBJECT_REQUIRE_DNS_AS_CN flag is set, do the following:

      1. If the request is for a machine certificate, the CA MUST set the CN of the Subject field of the issued certificate with the dNSHostName attribute of the requestor's computer object in the working directory. For this, the CA MUST invoke the processing rules in section 3.2.2.1.2 with input parameter EndEntityDistinguishedName set equal to the requester's computer object distinguished name and retrieve the dNSHostName attribute from the returned EndEntityAttributes output parameter.

      2. If the request is for a user certificate, the CA MUST set the Subject field of the issued certificate as a DN whose CN component value is attribute obtained from the User cn attribute in the working directory. For this, the CA MUST invoke the processing rules in section 3.2.2.1.2 with input parameter EndEntityDistinguishedName set equal to the requester's user object distinguished name and retrieve the cn attribute from the returned EndEntityAttributes output parameter.

    4. If CT_FLAG_SUBJECT_REQUIRE_EMAIL is set, the CA MUST set the Subject field of the issued certificate as a DN whose E component value is obtained from the value of the mail attribute of the requestor's user object in the working directory. For this, the CA MUST invoke the processing rules in section 3.2.2.1.2 with input parameter EndEntityDistinguishedName set equal to the requester's user object distinguished name and retrieve the mail attribute from the returned EndEntityAttributes output parameter.

    5. If the CT_FLAG_NO_SECURITY_EXTENSION flag is not set, the CA MUST add the szOID_NTDS_CA_SECURITY_EXT security extension, as specified in section 2.2.2.7.7.4, to the issued certificate with the value set to the string format of the objectSid attribute obtained from the requestor’s user object in the working directory. For this, the CA MUST invoke the processing rules in section 3.2.2.1.2, with input parameter EndEntityDistinguishedName set equal to the requester's user object distinguished name, and retrieve the objectSid attribute from the returned EndEntityAttributes output parameter.

  3. If CT_FLAG_ENROLLEE_SUPPLIES_SUBJECT is set, then the CA MUST use the subject and subject alternative name information provided in the certificate request. If no subject name is provided in the request, the CA MUST reject the request.

  4.  If CT_FLAG_ENROLLEE_SUPPLIES_SUBJECT is set and CT_FLAG_NO_SECURITY_EXTENSION is not set, then the CA MUST add the szOID_NTDS_CA_SECURITY_EXT security extension (section 2.2.2.7.7.4) to the issued certificate, that is, if it is provided as an extension in the request.

  5. If the CT_FLAG_SUBJECT_ALT_REQUIRE_UPN or CT_FLAG_SUBJECT_ALT_REQUIRE_SPN flag is set, the CA MUST add the value of the userPrincipalName attribute from the requestor's user object in the working directory to the subject alternative name extension of the issued certificate. For this, the CA MUST invoke the processing rules in section 3.2.2.1.2 with input parameter EndEntityDistinguishedName set equal to the requester's user object distinguished name and retrieve the userPrincipalName attribute from the returned EndEntityAttributes output parameter.

  6. If the CT_FLAG_SUBJECT_ALT_REQUIRE_EMAIL flag is set, the CA MUST add the value of the mail attribute from the requestor's user object in the working directory to the subject alternative name extension of the issued certificate. For this, the CA MUST invoke the processing rules in section 3.2.2.1.2 with input parameter EndEntityDistinguishedName set equal to the requester's user object distinguished name and retrieve the mail attribute from the returned EndEntityAttributes output parameter.

  7. If the CT_FLAG_SUBJECT_ALT_REQUIRE_DIRECTORY_GUID flag is set, the CA MUST add the value of the objectGuid attribute from the requestor's user object in the working directory to the subject alternative name extension of the issued certificate. For this, the CA MUST invoke the processing rules in section 3.2.2.1.2 with input parameter EndEntityDistinguishedName set equal to the requester's user object distinguished name and retrieve the objectGuid attribute from the returned EndEntityAttributes output parameter.

  8. If the CT_FLAG_SUBJECT_ALT_REQUIRE_DOMAIN_DNS flag is set, the CA SHOULD<130>:

    1. The CA SHOULD retrieve a handle for the information policy using the LsarOpenPolicy method ([MS-LSAD] section 3.1.4.4.2 ), with the SystemName parameter set as the dNSHostName attribute from the requestor's computer object, all fields of the ObjectAttributes set to NULL, and the DesiredAccess parameter set to POLICY_VIEW_LOCAL_INFORMATION.

    2. The CA SHOULD obtain the requester's computer DNS Domain Information by using the LsarQueryInformationPolicy method ([MS-LSAD] section 3.1.4.4.4), with the PolicyHandle parameter set to the value obtained in the previous step, and the InformationClass parameter set to PolicyDnsDomainInformation.

    3. The CA MUST add the value of the Name and DNSDomainName field in the returned DNS Domain Information from the previous step, to the subject alternative name extension of the issued certificate.

  9. If the CT_FLAG_SUBJECT_ALT_REQUIRE_DNS flag is set, the CA MUST add the value of the dNSHostName attribute from the requestor's computer object in the working directory to the subject alternative name extension of the issued certificate. For this, the CA MUST invoke the processing rules in section 3.2.2.1.2 with input parameter EndEntityDistinguishedName set equal to the requester's computer object distinguished name and retrieve the dNSHostName attribute from the returned EndEntityAttributes output parameter.
