The Keycloak SAML adapter for Wildfly26 is not working. Is SAML not supported by Keycloak for Wildfly26?
I upgraded from Wildfly24 and migrated from legacy-security to Elytron. I have installed Keycloak20.0.3 modules to Wildfly26 and I have run the adapter-elytron-install-saml.cli. Upon startup I get this when it tries to deploy my web application:

Currently there are no Keycloak adapters available for Wildfly 26.
Currently there is only support for Wildfly versions <= 23. See https://www.keycloak.org/downloads
