[keycloak-user] enable CORS

[lists]

Hi,

We are using keycloak as a SAML2 IdP for a web application (SOGo). 
Logging on works fine, however, after a while SOGo stops working.

I asked SOGo support to take a look at this, and they told me: "You'll 
need to enable CORS headers on our IdP keycloak.ourcompany.com so I can 
continue the debugging. The redirect is currently blocked for this reason."

I cannot find any keycloak toggle that would enable CORS headers. Could 
anyone tell me how to do this..?
