        true in all cases since this LoginModule should not be ignored.
        Throws:
        FailedLoginException - if the authentication fails.

        LoginException - if this LoginModule is unable to perform the authentication.
      • commit

        public boolean commit()
                       throws LoginException

        This method is called if the LoginContext's overall authentication succeeded (the relevant REQUIRED, REQUISITE, SUFFICIENT and OPTIONAL LoginModules succeeded).

        If this LoginModule's own authentication attempt succeeded (checked by retrieving the private state saved by the login method), then this method associates a PrincipalImpl with the Subject located in the LoginModule. If this LoginModule's own authentication attempted failed, then this method removes any state that was originally saved.

        Specified by:
        commit in interface LoginModule
        Returns:
        true if this LoginModule's own login and commit attempts succeeded, or false otherwise.
        Throws:
        LoginException - if the commit fails.
      • abort

        public boolean abort()
                      throws LoginException

        This method is called if the LoginContext's overall authentication failed. (the relevant REQUIRED, REQUISITE, SUFFICIENT and OPTIONAL LoginModules did not succeed).

        If this LoginModule's own authentication attempt succeeded (checked by retrieving the private state saved by the login and commit methods), then this method cleans up any state that was originally saved.

        Specified by:
        abort in interface LoginModule
        Returns:
        false if this LoginModule's own login and/or commit attempts failed, and true otherwise.
        Throws:
        LoginException - if the abort fails.
