java - 从 Java 服务器获取登录用户的 NT ID

Question

我将在服务器中托管我的应用程序。我只想获取登录到我的应用程序的用户的 NT ID。如果有人有答案，请分享？

system.getremoteUser()并将system.getProperty返回托管机器名称。

If you are specific about NT ID fetching in Java, this might work

com.sun.security.auth.module.NTSystem NTSystem = new
            com.sun.security.auth.module.NTSystem();
    System.out.println(NTSystem.getName());
    System.out.println(NTSystem.getDomain());
    System.out.println(NTSystem.getUserSID());

But for a webapplication context where you have NTLM authentication, you should be having NTLM (Windows) users as your application users as-well (this is a general case).

It would be better to query NTLMRealm (in Tomcat) or store user identity (SID etc) in a context (this can be session based or specific custom server-side implementation) while authenticating user via NTLM. Now use this context to retrieve NTLM properties of users (SID, GroupID etc) logged-in.
