How to enter credentials (Authorize object) in a web service call? - web-services

Question

I followed the advice provided here and it worked like a charm. Right now, I'm connecting to the server and calling a method named GetFunctionalityTest. The only input to it is a string, which can be seen in the GetFunctionalityTest.m file. So far so good.
Then I attempted to call the real service named GetSections whose signature according to the file GetSections.m is as follows.
function GetSectionsResult = GetSections(obj,auth)
% GetSections(obj,auth)
% Input: auth = (Authorize)
% Output: GetSectionsResult = (ArrayOfString)
values = { auth, };
names = { 'auth', };
types = { '{WSPro.HostingWebservice}Authorize', };
soapMessage = createSoapMessage( ...
'WSPro.HostingWebservice', ...
'GetSections', values,names,types,'document');
response = callSoapService( obj.endpoint, ...
'WSPro.HostingWebservice/GetSections', soapMessage);
GetSectionsResult = parseSoapResponse(response);
The definition provided by the server is as follows.
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi=...>
<soap:Body>
<GetSections xmlns="WSPro.HostingWebservice">
<auth>
<uid>string</uid>
<pw>string</pw>
</auth>
</GetSections>
</soap:Body>
</soap:Envelope>
My problem is that I can't specify the authorization syntax-wise. As far I understand, it's supposed to consist of two strings somehow but I haven't get it to work. I've tried to compound those as follows.
myAuthorization = ['user', 'pass'];
myAuthorization = {'user', 'pass'};
myAuthorization = ['user' 'pass'];
myAuthorization = {'user' 'pass'};
Nothing helped. I just got a bunch of errors.
Error using callSoapService (line 147)
Unspecified Fault: SOAP Fault: Server was unable to process request.
---> The parameterized query
'(#uid nvarchar(99)) SELECT PassW FROM UserData WHERE UserId = #' expects the parameter '#uid', which was not supplied.
I've browsed all the files automatically created for me and there's no definition of Authorize not ArrayOfString. I'm guessing it's something that the server defines, since I get no hits on those in MatLab documentation.
How can I specify the credentials for authorization?
Where can I look up how MatLab maps Authorization?

As noted above:
The SOAP Authentication happens through SOAP Header and not SOAP Body.This link might give you an idea of how SOAP XML should look in case of authentication :
