401 causes CORS error
by Pavel Maslov
Hi all,
I've observed this issue for a long time now. Standard scenario: a backend
app secured with Springboot Adapter + a frontend app which uses keycloak.js
library. Two clients are configured (*public* for token acquisition + *bearer
only* for REST calls).
Allowed CORS origins are set to * (Web Origins field for the public client).
application.properties has *keycloak.cors *set to *true*. REST controller
has *@CrossOrigin *annotation.
Everything works as expected. Until: the frontend app sends an erroneous
token in the Authorization header (e.g.: "Bearer blablabla"). As a result,
I get a CORS error, which says:
*Access to XMLHttpRequest at 'https://xxxxxx.herokuapp.com/items
<https://xxxxxx.herokuapp.com/items>' from origin 'http://localhost:1234
<http://localhost:1234>' has been blocked by CORS policy: No
'Access-Control-Allow-Origin' header is present on the requested resource.*

If I look at the preflight request though, then the
*Access-Control-Allow-Origin* header is indeed set.

Why that error message then? I must admit this confused me multiple times,
as I thought that I had issues with CORS. Also the frontend logic is
undermined, as I should include a custom interceptor (which I don't want to
do heheh). I tried both 4.8.3.Final and 5.0.0 - same result.
Any ideas? Thanks in advance!

Keycloak cluster setup on Openshift
by Jon Huang
Dear Keycloakers
On my local environment, I set up Keycloak cluster with multi-cast and it's
OK.
However, there are some issues which might be related to infinispan when I
migrate to Openshift with KUBE_PING.
(btw, I tested with Keycloak version: 4.8.1 docker version)
I put detail log in attachment and hope it helps. (log below is abstract
version)
It seems that infinispan timeout and not working correctly (which works in
my local environment though)
Does anyone have same experience on Openshift?
Thanks
