Hi,
I'm using CAS (Central Authentication Service) from Jasig in a client JSF app running on tomcat 6 server. I would like to limit the access to the app just for the users specified in my database rather than all the users which can be authenticated using that CAS service. When the user attempts to log in, I need to check if his username is also in my database's table user and if it is - allow the access to the app. Otherwise, I would like to redirect user to a page "You don't have permission to access this part of the application". So I need authorization as well. Is there a good way to authorize the users in jsf 2.0? Thanks in advance for any help/suggestions.
