Onvif - Invalid SOAP message or SOAP version mismatch

Question

I have really been confused with Onvif Authentication.

I have failed to execute onvif commands both on AXIS ans SONY cameras.

Here is the code generating a request:

procedure RebootDevice(dev: Device; Username, Password: string);
var
  sdt: SystemDateTime;
  Created: string;
  Nonce: string;
  Nonce64: string;
  Password64: string;
  Header: Security;
begin
  sdt := dev.GetSystemDateAndTime;
  Created := SystemDateTimeToStr(sdt.UTCDateTime); // yyyy-MM-ddTHH.mm.ss.000Z
  Nonce := '1234';
  Nonce64 := Base64Encode(Nonce);
  Password64 := Base64Encode(HashSHA1(Nonce+Created+Password));
  Header.UsernameToken.Username := Username;
  Header.UsernameToken.Password.Type := 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1.0#PasswordDigest';
  Header.UsernameToken.Password.Text := Password64;
  Header.UsernameToken.Nonce.EncodingType := 'http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary';
  Header.UsernameToken.Nonce.Text := Nonce64;
  Header.UsernameToken.Created := Created;
  SetHeader(Header)
  dev.SystemReboot;  // <---- Error in here
end;

Generated SOAP XML:

<?xml version="1.0"?>
<SOAP-ENV:Envelope 
    xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsd="http://www.w3.org/2001/XMLSchema"

                <NS1:Nonce 
                    EncodingType="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-soap-message-security-1.0#Base64Binary">
                    MTIzNA==
                </NS1:Nonce>
                <Created>
                    2004-01-03T08:20:09.000Z

    <SOAP-ENV:Body 
        xmlns:NS2="http://www.onvif.org/ver10/device/wsdl"
        SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
       <NS2:SystemReboot/>
    </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Troubleshooting hints:

• First, try to access the service with a tool like SoapUI and verify it sends the expected response
• Compare the request (header and body) of SoapUI and Delphi

Or

• capture the HTTP traffic with Fiddler or Wireshark and compare the Delphi / OnvifDM requests
