  • popup "do you have an account"
    • yes : login page
      • redirect to access request form
        • if already pending access request : info msg + redirect to study list
        • if already full access to study : info msg + redirect to study
    • no : account request page
• role & contact are no more to be set by the user
  • role
    • role is set (as a free string) by the study admin when he send the invitation email
    • the user doesn't see it directly and doesn't have to set it in the account request form
    • the role is then forwarded in the account request and displayed in user details by a shanoir admin (when he grants actual access to this new account)
  • contact
    • contact name (firstname + lastname) is automatically set when emitting an invitation (it's the inviter name)
    • transparent for the user as well
    • forwarded as well and displayed in user's details when the shanoir admin grants actual access
