Can you explain what exact problems are you running into and what your web application configs look like?
First of all, thanks for replying this post. Let me explain what is going on here:
Our customer wants to reach our application from their portal in order to start a process (wizard) in our app. We use form-based authentication:
The point here is that the customer does not want to perform the login process (never), they want a link in their portal to reach our application transparently. In order to solve it we thought to implement oAuth for authorization but due to they do not want login, we want to authenticate the user programmatically. That's the idea we have, you need to consider that we cannot change the current authentication, in addition to it according to my understanding we cannot use more than one auth method, in case we want to add an alternative one. Anyway, that's why we chose this idea.
That's it. Maybe we are wrong about it, I'd like to know your point of view.
Thanks in advance,
