How to check if user belongs to certain AD group in java

Question

I know it must be a very easy question, but I am new to java and find it hard to get exact code that I need. What I need to be able to do is to get currently logged in username

Answer 1

You can get all the groups without JNA like this:

String groups[] = (new com.sun.security.auth.module.NTSystem()).getGroupIDs();

Obviously this will work only on Windows, and even on Windows is the use of com.sun.* packages discouraged. See this for the explanation of the result.
