Here are a few suggestions where the problem might lie:
1) The clientaccesspolicy.xml
is not setup correctly. You might need to chenge the http-request-headers
or SOAPAction,Authorization and provide authorization.
2) Also you might have limited database permissions for the role you created for the IUSR IIS default user.
I would suggest you to check very carefully if you have performed all steps described in this
article. The clientaccesspolicy.xml
setup is at the end of it, but please be sure you have completed all steps.
Also you can try to break when there is an exception - in Visual Studio go to Debug -> Exceptions and mark all checkboxes. This may give you more information what is the problem.
