Re: [keycloak-user] How to handle roles from IDP manually when securing a web application with Keycloak/SAML/Wildfly

So, is this correct that: - your customer has the "foo" role configured in their Keycloak; - authors of the app expect that the user have the "bar" role; - neither your customer wants to create "bar" in Keycloak, nor programmers want to change their code to use "foo", and you're caught in the crossfire? Off the top of my head, there can be two solutions: 1) modify SAML adapter code and implement role mapping there - shouldn't be too tricky, but from now on you'll have to use modified adapter and update it with every Keycloak release (or maybe commit it to upstream, but I'm not sure it will be accepted); 2) deploy intermediary Keycloak, configure brokering between it and customer's one and use the role mapper trick. This could be made transparent for end-users, however will add a couple of redirects to the flow. And of course this will mean that you'll have to maintain yet another piece of software. Good luck!
