Hi Jure,
I made some changes to PTracker authentication in order to have Windows Authentication. In fact you just need to change CslaAuthentication attribute. The nicest thing about it is that you can have both at the same time.
If the users that is authenticated under Windows exists in the users table, it gets logged on with no further questions. Otherwise (the windows user name doesn't exist in the users table) the login window will ask for username/password. This is quite useful when you have an application on a client but your laptop is not in the client's domain. You can still use your laptop and login in the application using the application admin username.
