All, I am looking for a mechanism which makes use of "Forms authentication" and "Role based authorization". Requirement is my application should validate users belonging to different groups "Admin,guest,developer" and each group may consist of no of users. for ex: if i(developer) logs in with my id and pwd i should be redirected to web pages that are specific to me, likewise for admin and guest too. i am considering option of storing credentials in sessions and fetch the roles from db for access. Is this a feasible option. can anyone guide me?
