Also, I don't think it's worth implementing a new principal and a new login module. You can just using the out-of-box UnixLoginModule and NTLoginModule.

@wangweij I am trying to make use of UnixLoginModule with the new test case added with latest commit.
Looks like it turns out to be a positive test case without injecting some wrong `uid` or `gid` etc.
I tried to explore how we can programmatically induce a wrong `uid` or `gid` so that the stack trace which is expected to be printed when wrong credentials are fed.
Honestly I spent good amount of time and not getting how to get this test case into proper shape?
Could you please help?
