Use Single sign on with Box.com using company credential and ADFS 2.0 as Idp

Question

I want to create an c#.net application that allows users who have logged in to company domain by their username/password can interact with Box.net without authentication (SSO). The app flows as the following image

• Users login by their username/password to company network and call the application

• Application sends requests to Box.net, then box asks ADFS 2.0 for authentication

• Application provides ADFS the user credential, and then ADFS sends authentication result back to Box.net

• Box returns token to application and application use the token to do other actions such as uploading file, deleting files.

app flow

My question is:

- How can I request Box.net for single sign on from my application
As I have followed this instruction but it does not work Use SAML Single Sign-On to obtain OAuth access token or code for using Box.com API

- After obtaining the token from Box.net, how can I do actions to Box.net as uploading, deleting...

I do not see instructions on Box.net for single sign on integrations. please give me your ideas?

Answer 1

The clue is in the title - "SSO to obtain OAuth".

ADFS 2.0 does not support OAuth.

You need to do this via SAML - refer Single Sign On (SSO) with Box: For Administra​tors.
