[keycloak-dev] Generic servlet adapter?

[Marek Posolda]

I wonder if we should have some generic HttpServlet based adapter? It 
can be used for all the servlet containers, where we don't have proper 
adapter. We can create just HttpServletFilter and after the 
authentication, send forward the wrapped HttpServletRequest with few 
overriden methods (getRemoteUser, isUserInRole, logout, ...).

The disadvantage is that it's not tightly coupled with the container 
security (propagation to EJB etc) and security-constraints in web.xml 
won't work, so we will need to use something different (init-parameters 
in the filter maybe). I know we have proxy, but maybe this will fit even 
better for some environments?
