The 24.0.10-redhat-00001 variant of the keycloak-saml-adapter-galleon-pack used with EAP 8.0 Update 11 generates an invalid configuration, with elytron subsystem custom-realm and service-loader-http-server-mechanism-factory resources with 'module' attributes that point to a non-existent "org.keycloak.keycloak-saml-wildfly-elytron-adapter" module.

The value should be "org.keycloak.keycloak-saml-wildfly-elytron-jakarta-adapter".

A server with such a config will not start correctly.
