Hi Jan, If I comment out the jQuery "crossDomain: true" and "xhrFields: {withCredentials: true}" attributes of the XHR object then I do see the OPTIONS header in the web browser console. If I include the attributes I don't see OPTIONS. Is it possible preflight isn't needed if you've configured your client to use crossDomain? If forgot to include in my last email the final request HTTP status response code: it is 303. Is that a clue? What about all of the CORS options such as cors-max-age, cors-allowed-headers, cors-allowed-methods, etc. I am not including them in Wildfly standalone.xml currently. Are they needed to make this work? It doesn't seem to make a difference when experimenting, but I'm not sure what values to use...

My assumption is that 3.4.2+ Keycloak CORS implementation is broken and it doesn't support any JS cross-domain access at the moment.
