Hi,
it seems we are not adding CORS headers to error responses. Could you
create JIRA for it? We are returning JSON with error descriptions and
details, the only issue is that you were not able to read those error
details due to the CORS headers.

Hi,
I’m integrating a web application using angularjs 1.4.6 and keycloak
1.5.0.
The application and keycloak app-servers are on different ports.
The application works ok when the session is not expired.
After session expiration keycloak.updateToken() fails with
400 Bad Request. Chrome shows the following in the console:
XMLHttpRequest cannot load
http://localhost:8080/auth/realms/demo/protocol/openid-connect/token.
No 'Access-Control-Allow-Origin' header is present on the requested
resource. Origin 'http://localhost:9080' <http://localhost:9080%27> is
therefore not allowed access. The response had HTTP status code 400.
The behavior is same with Safari and Firefox.
If I get it right, this 400 response from keycloak shouldn’t be
interpreted as CORS failure by browsers?
This is keycloak response when session is alive:
--> HTTP/1.1 200 OK
X-Powered-By: Undertow/1
Server: WildFly/9
Access-Control-Expose-Headers:
Access-Control-Allow-Methods
Date: Tue, 29 Sep 2015 04:54:52 GMT
<http://airmail.calendar/2015-09-29%2010:54:52%20GMT+6>
Connection: keep-alive
Access-Control-Allow-Origin:
http://localhost:9080 <http://localhost:9080/>
Access-Control-Allow-Credentials: true
Transfer-Encoding: chunked
Content-Type: application/json
And this one with session expired:
--> HTTP/1.1 400 Bad Request
Connection: keep-alive
X-Powered-By: Undertow/1
Server: WildFly/9
Transfer-Encoding: chunked
Content-Type: application/json

So my concerns are:
1. Why CORS headers depend on session validity? This caused much
confusion for me,
because I thought there is a problem with CORS, until I understood
this was session problem.
2. I think it would also be great to have some more context on error
responses
(like returning some json with error description), because HTTP
responses are too generic.
