(Looks like this is the first DEPR announcement being posted in Discourse!)
We plan to deprecate and remove our use of the unsupported django-oauth2-provider library in favor of Django’s recommended django-oauth-toolkit library. This includes the removal of support for OpenIDConnect as it is currently implemented in the platform. We are targeting removal after Nov 18, 2019.
Please read https://openedx.atlassian.net/browse/DEPR-47 for more information and to post any questions/comments. The proposed deadline for comments before acceptance is Nov 4, 2019.
