Avalon as a LTI tool in a LMS

The purpose of setting Avalon up as an LTI tool in an LMS is to offer course-specific access and customized content verified by the LMS.

Set up Process

Add the LMS as an authentication provider. 

The authentication settings for LTI are added to config/authentication.yml with the other authentication providers. A new parameter called "hidden" was added to keep the LTI provider from showing up at the log in screen. Here is an example LTI authentication config block: 

- :name: Avalon LTI Oauth
  :provider: :lti
  :hidden: true
  :params:
    :oauth_credentials:
      key: 'secret'

The file config/lti.yml tells avalon where to look for user, class and lms information in the hash received from LMS. These are the default values that are hard-coded into our version of the gem omniauth-lti. You'll only need the lti.yml if any of these values are different for your LMS.
