[keycloak-user] keycloak does not send backchannel logout requests to Admin URL

[mn at fstrk.io]

I created a client in Keycloak and set up a test admin URL 
https://webhook.site/12c50381-0814-441a-82bb-1a68c8366a60 (this is a 
webhook testing site).

After that, I performed an OpenID login via this client, and then sent a 
logout request to Keycloak.


I did this a couple of times, and tried two ways of logging a user out:

- redirecting to 
http://.../auth/realms/myrealm/protocol/openid-connect/logout 
<http://127.0.0.1:8080/auth/realms/myrealm/protocol/openid-connect/logout>

- force logging out of the user via Keycloak admin interface: 
http://prntscr.com/pv1v76

The user indeed gets logged out. However, in both of these cases I don't 
see any requests coming out from Keycloak. The testing website shows 
zero registered requests.


How do I make this work?
