No I did not specify this anywhere. I tested removing the equivalent setting on the Keycloak side and it broke the authentication. I also tried removing SSO and it also failed. I need to investigate more because on different multisite installations I have not the same behavior for the same SAML settings on Discourse and Keycloak. Is it possible that there’s some bad interaction with SSO? E.g., one authentication mode taking over the other at some point?
