LinkedIn API Help for App

1. is there anyway to pull in the LinkedIn credentials automatically (on SSO people are forgetting their login credentials) then cannot get in the app 2. is there any way right now to import more of the profile from LinkedIn so people don't have to create a new profile? (now we can only import name, photo & email from LinkedIn) 3. Can a connection request be initiated from the app (without going on LinkedIn until going on to accept)? Thx - jo@noww.co
