I am running into problems trying to do SAML integration between an instance (let us say instA SP) Keycloak (Quarkus) 18.0.0 and another instance (instB IdP) both in production mode (with keystore configured in .conf file)
InstA : I configure SAML identity Provider and InstB I setup client by exchanging the SAML descriptor XML. When I try accessing the account console application in SP(inst A) - the redirection towards instB(idP) works well but fails to render the IdP login page for not being able to validate signature of the SP signed SAML Authn request.
Looking for some advice.
