problem with digest auth: msg#00078 php.nusoap.general

Hello,

I´m using nusoap to access a web service with the setCredential function
to use a password protected web service.

With basic auth it works perfectly but if I switch the blackbox (embedded
system) offering the webservice to use digest auth instead of basic I
can´t authenticate. The question I´m asking myself is if it is a problem
of my code, the webservice itself or nusoap...

I was just testing with a short testscript:

-------------------------------------------------------

<?PHP
require_once("nusoap.php");
$username = 'admin';
$password = 'somepasswd';

$soap = new soapclient("http://172.16.183.244/PBX0/user.soap";);
$soap->setCredentials($username, $password, 'digest');
$err = $soap->getError();

// Anlegen von Parameterarray
$params = array(
'user' => '_ADMIN_',
'appl' => 'PhoneBook Script'
);

// create Session
$session = $soap->call("Initialize",$params);
if (!$session)
{
echo ("false");
echo $err;
}
else
{
echo ("true");
echo $err;
}

echo 'Request: <xmp>'.$soap->request.'</xmp>';
echo 'Response: <xmp>'.$soap->response.'</xmp>';
echo 'Debug log: <pre>'.$soap->debug_str.'</pre>';

?>

-----------------------------------------------------------

Here is the reply I get from this script:

Switching both sides back to basic auth works again... Acsessing the
system using a web browser works with digest auth.

Any suggestions for my problem? I´m espicially worried about the line
"Authorization: Basic YWRtaW40dm9pcDpzb21lMQ==" in the header...

Thank you

Kind regards
Michael
