I assume you've exposed a SOAP web service. Perhaps I'm missing something, but I think the standard setting for a web service is basic authentication, as here:
This only then requires that you set up a System.User and provide them credentials to access the service.
@Eric: No that is not the same. The username password authentication expects a plain user id / password combination in the header, like so:
<soapenv:Header> <authentication> <username>user</username> <password>pwd</password> </authentication> </soapenv:Header>
A basic authentication token is not in the request header but a request parameter:
Authorization: Basic <token>
Couldn't you just expose the model as OData? SAP subscribes heavily to the standard and you can setup basic auth there.
Anybody an answer for this SAP webservice problem??
Is this problem solved on your end. I've the same issue here and the Mendix person here is not able to get it solved.
