Hi,
Got this working. It turns out that I didn't really understand the console screen. There were two fields on it - which my instinct told me were userid and password fields. but in reality, they were two different choices of how to log in. I was forever clicking on the first link - thinking it was the userid field, when it really was the link to only allow a kubeadmin login. The other field / link let me log into the system via the new identity provider.
I think the usability of this page can be improved by making it not look like an input field. Let only the link be rendered. Just my $0.02.
Regards,
Marvin
