JAAS Authentication Process:

  • Creating  an Instance of Login context-using the constructor- LoginContext(String,CallbackHandler)
  • The First paramenter takes the name of the configuration file
  • Second Parameter is a callbackhander it has a Handle() method-this passes the information to the loginModule.
  • An empty Subject is created before authentication begins-this subject is passed to the login modules.On Success the SUbject is attached with credentials.
  • login() method is called to instiate the  login process-after success the application can retrive the Subject using getSubject();
  • on failure throws authentication failure exception.
