How do I access SharePoint web services behind a Windows-based-authentication or ISA server?

Question

I want to access sharepoint webservices behind a windows based authentication/ ISA server so that I can getallitems of a list.

I been looking for a tutorial to do this or come up with my own logic but no success. However I found this tutorial which does what I want, but for forms authentication:

I actually want to build a Windows 7 gadget, so all I can use is:

• HTML
• Script
• SOAP/XML/XHR

Here's a blog post that does the same thing, but with no authentication at all:

Jquery $.ajax SOAP webservices

Answer 1

if you can do something with User Interface then you can easily do that thing with Coding

But building a Gadget the way you are trying is not really coding.

Here is a tutorial on how to build a gadget using C#. Once you have that down you would then need to learn how to use the SharePoint web services.

Then you would generate a proxy class from the list web service (http:///_vti_bin/Lists.asmx.).

Then you would need to learn to call the web service and parse the returned data. You could do this all with authentication because you are using C#.

Answer 2

The problem is.. you can't really authenticate the user using JavaScript. At least, not like in C# where you can just provide credentials or use the user's DefaultNetworkCredentials.

The only thing I can think of to get this to work is by loading a page from the SharePoint server. Hopefully, since it is Windows auth, the page will load automatically with the current user's credentials.

Maybe try creating a HTML page that is calling the SharePoint webservices on the SharePoint server (in a document library for example) and then load that page in an IFRAME in your gadget.
