[ARCHIVED] How LTI 1.3 Name and Role Provisioning works?

[gregzhang]

Could someone explain how LTI 1.3 Name and Role Provisioning works?

Document just says "The Tool Consumer (typically an LMS) launches the Tool Provider. The Tool Provider performs a request for a membership list. Tool Consumer responds with the list for the requested organization context."

But how exactly this work? When I launch the tool, it returns some values but I don't see all user list for that course. 

Thanks

Greg
