2个Java线程可以作为两个不同的Kerberos用户进行身份验证（在同一个进程中）吗？

Question

How can 2 Java threads (of the same process, same machine) each create their own Kerberos ticket?

My concern is that usually, once a Kerberos ticket is created on a machine, it will be used by all other processes on the machine.

I am planning to use Java's default Kerberos libraries , but I haven't started yet so I am open to any suggestion (must be open-source).

A small hello world that connects to http://server via Kerberos as thread1-user1-password1 and thread2-user2-password2 would be awesome!

Context: I want to write a load-testing tool:

• My tool launches 100 threads,
• Each thread logs in as a different Kerberos user,
• Once logged, each thread starts sending requests.

Doing the load-test as several users is important, as each user has its own cache etc.
Kerberos can not be disabled/circumvented, because the purpose is also to test Kerberos.

The authentication belongs to the GSS context, not the JVM. You can have as many contexts as you like, ergo as many tickets and authentications as you like.
