Having been away from WildFly for 5 years, I find myself tasked with creating a minimal OAuth 2.0 IDP implementation, and would like leverage the new Elytron components in an appropriate way.
Logically, at a 1000-foot level, it would seem that I should be able to implement the token endpoint and leverage a custom authentication realm implementation (which, ideally, could leverage a properties-realm for the user/password validation, at least initially) and, when login succeeds, generate the bearer token for the client. Then, the "main" app would need to validate the bearer token either using the existing database table or an "introspection" URL (which would then also need to be implemented by our new OAuth 2.0 webapp). If we do provide an introspection URL, would the provided token-realm cache results so that introspection is not required for repeated requests?
I apologize for the meager information (I am not trying to withhold anything -- I am just not sure how much is relevant, just to get me pointed in the right direction) and would like to say "thanks" in advance for any pointers anyone can provide. I will try to look through the copious documentation and quickstart links I've found so far...
