Q42 Which file holds the details of users and groups in adf?Answer:Users and Groups we usually create in Security part at the time of enabling security on your application by default someof the files gets created inside Application Resources, Inside that we will find jazn-data.xml file, once we open that file wecan have access to create the user profiles, Application Roles and Enterprise roles, So your application level roles isassigned to the users whom ever are created in your user profile, So each and everything from user roles to enterpriseroles your are giving inside your jazn-data.xml file.
