Hi all,
I created a connected app with Full and Web scope included. I'm able to retrieve the salesforce instance and access token and query the salesforce objects with rest apis. 
However when I try to access the Frontdoor.jsp with the call https://inst.salesforce.com/secur/frontdoor.jsp?sid=<access_token>&retURL=<ret_url>
I always get the login page.
The same call done by using a session id (taken from a Firefox cookie) works.
In the documentation of frontdoor.jsp is written that an access_token can be passed if the connected abb has full or web scope included, but mine doesn't work... do you have any hint for this?
