Force Authentication Not Working

Hello,

I’m using Keycloak as an identity broker. I have an OIDC client configured for my server and an external IDP that uses SAML. Under the IDP settings, I’ve turned “Force Authentication” on. I expected that when the user logs out and then tries to log back in, the user would be forced to re-authenticate with their IDP, but this isn’t happening. How does one enforce this behavior?
