Hi, I have registered an app with /_layouts/15/appregnew.aspx, because I made a remote web application without the .NET environment. The app shows the skydrive-pro folder structure of the logged-in sharepoint user.
The oauth process follows this approach: http://jomit.blogspot.nl/2013/03/authentication-and-authorization-with.html
My question is: why is it that the user has to trust the app everytime it uses it during the oauth process? Does this happen with on-premise sharepoint apps as well? My idea about oauth is that the user trusts an app 1 time, and after that only has to login to use it (if he/she is not already logged in).
NOTE: I use a proxy to pass all the calls from javascript to the SharePoint api. I don't use the SP lib, and no C#
thanks
