Hey there @dansup
as you did not react to the SSO Issue nor the Pull Request yet I'd like to raise attention on this before it gets stale again. There is a modest demand for this. Someone even build a container image with the patches applied running it in prod on their instance. Much appreciated if you'd find the time to handle this or at least comment what is currently blocking this community effort from progressing :blobcatcoffee:
