[wildfly-dev] Accessing an HTTP header in a custom Elytron domain

Hi, I have a web frontend application that is communicating with a beckend REST service. I would like the web frontend to automatically authenticate/authorize with the REST services by including the username and roles of the authenticated user as HTTP headers in the REST call. I found a wildfly quickstart (http-custom-mechanism) which allows me to the authentication part. However, I haven't not been able to figure out how to provide the roles in the same fashion. In the case of the quickstart I mentioned, it would be something like adding an additional HTTP header to the curl call, like so: -H "X-ROLES:admin,ops" which would result in the user being assigned the "admin" and "ops" roles in the REST service. Does anyone have any pointers on how I can do this? Thanks in advance.
