Hi,
in our scenario, we use a single instance of Keycloak v20 to manage three realms. Ideally, we would like to bind those to three different hostnames:
public -> login.mycompany.com
intranet -> intranet.mycompany.com
certificate -> secureintranet.mycompany.com
Our load balancer takes care of SSL termination and directs all traffic to those three realms to the Keycloak instance. Only the first one is published on the Internet, the others are only accessible inside the LAN/VPN. However we found out that a malicious actor can manually change the login URL on the public hostname to try an access with the intranet credentials, i.e. visiting https://login.mycompany.com/auth/realms/intranet/...
As far as I can see no current option allows limiting access to specific realm endpoints only for requests coming from specific hostnames.
Is this correct? Do you think it would be an useful feature?
