Re: [keycloak-user] Token exchange cross realm

Hi, I tried giving the app1 the credentials of the R1_for_R2 (the client used for the federation on the IDP2) and i could exchange the token from the app1 to a token on the app2 ! However that's far from what we wish the app1 has now the power to exchange any token on R2 configured with the Client R1_for_R2, so i can have only one application on each side with token exchange activated without security issues. If it makes sense, i can propose an update on the documentation, specifying the application needs the credentials of the second IDP to do the exchange.
