MBO Authentication error

Hi gurus,

Let me explain the environment: SAP -> GW -> SUP - REST service (simple right? )

Here is the requirement: before using the app, the user needs to log in.

Here is the problem: After reading allot on SCN about the authentication, I still couldn't manage to make it work.

Here are some of the links:

and many more...

Here is my development:

a) The REST Service connection details

b) The MBO created on the REST Service Connection mentioned at point a)

c) The flow design:

d) Log in Screen:

I didn't manage to make this work. I might have missed some things, but this is what I've got so far.

I know that the link works, I'v tested it from REST client and "Preview" in Mobile Development Environment.

After I fill the 2 edit-boxes, I go to the next screen and when I press the "Online request" button, I'm taken to the login screen again (I think due to the checkbox "Show credential screen on Authentication failure" of the button)

Any suggestions on what I'm doing wrong or incomplete?

Thanks,

Marius
