The LTI adapter type is an Oauth 1.0 signed request which conforms to the LTI 1.1 standard. In an LTI 1.1 launch, you must provide either the lis_person_sourcedid or ext_user_username property containing the batch_uid/external ID of the user to log in. You may provide a Redirect Parameter to forward the user to a specific location in Learn.
