[keycloak-user] Role to claim mapping

I'm trying to test the Identity broker to achieve cross domain sso, this is what I have done: 1 - Installed jboss 6.4 eap + keycloak + keycloak eap6 adapter in host A 2 - Installed jboss 6.4 eap + keycloak in host B 3 - In host A, I added an oidc Identity Provider (importing host B openid connect configuration). 4 - In host A, I created an application (appa.war) that will try to use the broker to authenticate. I added security to the app (only user with role "user" will be able to access some parts) 5 - In host B, I added 2 oidc clients (the broker from host A and appb, appb (appb.war) is a simple application developed to log in using oidc) 6 - In host B, I created a role "testrole" inside appb and a user "testuser", then I added that role to the user. I couldn't find out how to map the role "testrole" to a claim that will be sent to the broker once the user has authenticated. Is there a way to do that? After I accomplish that I plan to map that claim to the role appa.user.
