public final class AuthPermission
extends BasicPermission

This class is for authentication permissions. An AuthPermission contains a name (also referred to as a "target name") but no actions list; you either have the named permission or you don't.

The target name is the name of a security configuration parameter (see below). Currently the AuthPermission object is used to guard access to the Policy, Subject, LoginContext, and Configuration objects.

The possible target names for an Authentication Permission are:

      doAs -                  allow the caller to invoke the
                              Subject.doAs methods.

      doAsPrivileged -        allow the caller to invoke the
                              Subject.doAsPrivileged methods.

      getSubject -            allow for the retrieval of the
                              Subject(s) associated with the
                              current Thread.

      getSubjectFromDomainCombiner -  allow for the retrieval of the
                              Subject associated with the
                              a SubjectDomainCombiner.

      setReadOnly -           allow the caller to set a Subject
                              to be read-only.

      modifyPrincipals -      allow the caller to modify the Set
                              of Principals associated with a
                              Subject

      modifyPublicCredentials - allow the caller to modify the
                              Set of public credentials
                              associated with a Subject

      modifyPrivateCredentials - allow the caller to modify the
                              Set of private credentials
                              associated with a Subject

      refreshCredential -     allow code to invoke the refresh
                              method on a credential which implements
                              the Refreshable interface.

      destroyCredential -     allow code to invoke the destroy
                              method on a credential object
                              which implements the Destroyable
                              interface.

      createLoginContext.{name} -  allow code to instantiate a
                              LoginContext with the
                              specified name.  name
                              is used as the index into the installed login
                              Configuration
                              (that returned by
                              Configuration.getConfiguration()).
                              name can be wildcarded (set to '*')
                              to allow for any name.

      getLoginConfiguration - allow for the retrieval of the system-wide
                              login Configuration.

      createLoginConfiguration.{type} - allow code to obtain a Configuration
                              object via
                              Configuration.getInstance.

      setLoginConfiguration - allow for the setting of the system-wide
                              login Configuration.

      refreshLoginConfiguration - allow for the refreshing of the system-wide
                              login Configuration.
 

The following target name has been deprecated in favor of createLoginContext.{name}.

      createLoginContext -    allow code to instantiate a
                              LoginContext.
 

javax.security.auth.Policy has been deprecated in favor of java.security.Policy. Therefore, the following target names have also been deprecated:

      getPolicy -             allow the caller to retrieve the system-wide
                              Subject-based access control policy.

      setPolicy -             allow the caller to set the system-wide
                              Subject-based access control policy.

      refreshPolicy -         allow the caller to refresh the system-wide
                              Subject-based access control policy.
