Cannot authenticate

[jalleyne]

Hi, Im trying to use your module and i am running into issues with the response from LinkedIn.

/authenticate/__cb__/linkedin?error=invalid_request&error_description=You+need+to+pass+the+%22state%22+parameter

this is what i get returned to my callback. from what i can tell your api doesnt send the state parameter and i can't see anywhere to add this using your functions.

looking into your code i see a method Strategy.prototype.authorizationParams but it is never called in your code.

Is there something im missing or is this parameter recently enforced as required by linkedin? thanks

I might be having the same issue as yourself. I'm running a LocomotiveJS app with Node, and authenticating with the LinkedInStrategy responds with a callback url of the form:

http://domain.com/authenticate/linkedin/callback?code=LONG-STRING-OF-CHARACTERS&state=some+state

The current configuration is as follows:

// Locomotive routes                                                                                                                                                                                                                      
this.match('authenticate/linkedin/', passport.authorize('linkedin', { state: 'some state' });

})); 

All this results in a 404.
