This module seems to be quite an old module. I haven't tried it myself recently, but i can't see anything that wouldn't work now in our cloud.
Unfortunately I don't get access to linkedin. I have created an app in linkedIn, see the image. After that, I created the module into a new project, copied the ID and secret to the project-constants LinkedIn.ConsumerKey and LinkedIn.ConsumerSecret. Save and Run and that should work. Nevertheless I get the standard error-message and in the console I get access denied.
li: com.mendix.core.CoreRuntimeException: com.google.code.linkedinapi.client.oauth.LinkedInOAuthServiceException: oauth.signpost.exception.OAuthCommunicationException: Communication with the service provider failed: access denied (java.util.PropertyPermission debug read)
at LinkedIn.AuthenticateLinkedIn (JavaAction : 'Call 'GetLinkedInLoginURL'')
Do I miss a step here? Why does Linked in deny me access?
