I am trying to set up an ADFS identity provider based upon this blog post.
Finally, I manage to log on at ADFS, but after redirecting to Keycloak, I see a page with
“An internal error has occurred”
message. In the server logs I see:
ERROR [org.keycloak.services.error.KeycloakErrorHandler] (default task-1) Uncaught server error: org.keycloak.broker.provider.IdentityBrokerException: Could not process response from SAML identity provider.
The SAML response itself doesn’t look too broken. How can I debug this problem?
