Hi Cindy - before I dive in I wanted to thank you for writing the OpenID Connect (and PluggableAuth) extension.
I'm looking for some help debugging an issue with OIDC. Like the title, I'm experiencing a redirect loop after my SSO provider redirects to Special:PluggableAuthLogin. My SSO provider and Special:PluggableAuthLogin redirect back and forth to each other infinitely.
It looks like my SSO provider (Keycloak) is sending the correct query parameters back to PluggableAuthLogin.
I'm running: MW 1.39.10; PluggableAuth 7.1.0 (db07c04); OpenID Connect 8.0.3 (0cd85ca)
Here is a debug log too: Topic:Yg0wtew7lklqijwy
