This completes the work started in https://github.com/edx/edx-platform/pull/19453 to use the LMS login and registration for Studio, rather than Studio providing its own implementation. LMS login/registration are being used for the following reasons: 1. LMS logistration properly handles all SSO integrations. 2. A single logistration is simpler to maintain and understand. 3. Allows Studio to work more like all other IDAs that use LMS logistration. The original switch to use LMS logistration for Studio also added the toggle `DISABLE_STUDIO_SSO_OVER_LMS` to provide the community some additional time for switching. This commit removes this toggle, which at this point means all deployments will use the LMS logistration. This change requires sharing cookies across LMS and Studio. Should that prove to be a problem for certain Open edX instances, there are discussions of possible alternative solutions. See https://github.com/edx/edx-platform/pull/19845#issuecomment-559154256 Detailed changes: * Fix some Studio links that still went to old Studio signin and signup. * Remove DISABLE_STUDIO_SSO_OVER_LMS feature toggle. * Remove old studio signin and signup pages and templates. * Fix url name "login", which had different meanings for Studio and LMS. * Use the following settings: LOGIN_URL, FRONTEND_LOGIN_URL, FRONTEND_LOGOUT_URL, and FRONTEND_REGISTER_URL. * Redirect /signin and /signup to the LMS logistration. * Add custom metric `uses_pattern_library`. * Add custom metric `student_activate_account`. * Add Django Settings to allow /signin, /signup, and /login_post to be disabled once ready. This work also relates to ARCH-218 and DEPR-6. ARCH-1253
Status: Active Responsibilities ================ The user_api app is currently a catch all that is used to provide various apis that are related to the user and also to features within the platform. Intended responsibility: To manage user profile and general account information and to provide APIs to do so easily. Direction: Decompose =============== Currently this app is a catch all for many user related information even when that information sholud really belong in a different app. If you are building a feature and need to provide information about a user within the context of your feature, you should localize that API to your feature and make your assumptions about what user information you need clear. For example authentication related APIs have already been moved to the user_authn django app. Glossary ======== More Documentation ==================
