Test Accounting for authentication failures of uni-transaction logins

• Record the time T0 for use later in this test
• For each of the supported RecordResponse.service_request.service_type that is authenticated per-transaction:
  • Connect to the DUT, recording the local and remote IP addresses and port numbers,
  • Provide invalid user credentials (including an empty username, unconfigured username, empty password, invalid password, wrong SSH key/certificate, etc),
  • disconnect
• Establish gNSI connection to the DUT.
• Call gnsi.acctz.v1.Acctz.RecordSubscribe with RecordRequest.timestamp = T0
• Verify that accurate accounting records are returned for the commands/RPCs authentication failures.
• If start/stop accounting is supported, each authentication failure should have an accompanying ONCE accounting record.
• For each RecordResponse correlated to each connection made above, check/confirm that:
  • session_info. :
    • .{layer4_proto, local_address, local_port, remote_address, remote_port}, ip_proto must match those recorded earlier
    • channel_id = 0 for ssh and grpc.
    • .tty must be populated and correct, if applicable to the platform & access method, else omitted
    • .status must equal ONCE:
      • .authen.type must equal the authentication method used.
      • .authen.status must equal FAIL, and cause should be populated.
      • .authen.cause should be populated with reason(s) for the failure.
    • .user.identity must match the username sent to authenticate to the DUT
    • .user.privilege_level should be omitted.
  • timestamp is after (greater than) RecordRequest.timestamp
  • session_info.service_request.serivce_type must equal the service used.
  • cmd_service. or grpc_service:
    • .service_type must equal the service used
    • all other fields should be omitted.
  • for authorization:
    • all other fields should be omitted.
  • task_ids might be populate with platform-specific information
