                    The flag attribute controls how a login module
                    participates in the overall procedure.
                    Required - The LoginModule is required to succeed. If it
                    succeeds or fails, authentication still continues to proceed
                    down the LoginModule list.

                    Requisite - The LoginModule is required to succeed. If it succeeds,
                    authentication continues down the LoginModule list. If it fails,
                    control immediately returns to the application (authentication does not proceed
                    down the LoginModule list).

                    Sufficient - The LoginModule is  not required to succeed. If it does
                    succeed, control immediately returns to the application (authentication
                    does not proceed down the LoginModule list). If it fails,
                    authentication continues down the LoginModule list.

                    Optional - The LoginModule is not required to succeed. If it succeeds or
                    fails, authentication still continues to proceed down the
                    LoginModule list.

                    The overall authentication succeeds only if
                    all required and requisite LoginModules succeed. If a
                    sufficient LoginModule is configured and succeeds, then only
                    the required and requisite LoginModules prior to that
                    sufficient LoginModule need to have succeeded for the overall
                    authentication to succeed. If no required or requisite
                    LoginModules are configured for an application, then at least
                    one sufficient or optional LoginModule must succeed.
