+    Some installations have a marketing site front-end separate from

+    to the student dashboard instead of the login page.)
+
+    Since social auth uses Django's native `login()` method, it bypasses

+    we need to send a response to the user in order to set the cookie.
+    On the other hand, we don't want to drop the user out of the pipeline.
+
+    For this reason, we send a redirect back to the "complete" URL,
+    so users immediately re-enter the pipeline.  The redirect response
+    contains a header that sets the logged in cookie.
