Awesome, thanks for this!!!
We’ve been testing it on Phoenix 1.4 and have our login working – but logout is throwing an error.
In login – the conn params includes idp_id_seg which seems to be pulled from glob and it looks correct.
But in logout, our idp_id_seg is missing and doesn’t seem to be extracted from the glob path_params (which are what we’d expect, with the idp in the 2nd position).
We end up getting:
invalid_request unknown IdP
Any ideas what might cause logout to fail when login works?
Thanks so much for your work on this! Really helping to get Elixir into enterprise environments
