SSO for Brighter Tomorrow Map

@zofrex @tmcnulty @syl@bob too as you found the issue last time. The SSO settings on the testing server are not working. I copied over all the details in the admin section of Discourse, and checked the url here: https://github.com/focallocal/fl-maps/blob/master/deployment/testing/settings.enc.json

I’m not sure what the error is, but it is occurring when a user tried to login on the testing server
