This package provides the classes and interfaces needed to implemenet and program different methods of users' authentification and role based users' authorization. All subjects' authentification and role based authorization are strongly coupled with the java.security file that, as always, is the ultimate arbiter of all matters secure in Android. For example the class javax.security.auth.SubjectDomainCombiner updates the ProtectionDomains associated with the actual class with the subjects defined therein.
