Kerberos authentication from virtual machine (Ubuntu)

Question

My company gave me a windows7 computer, however I prefer to work within a virtual machine running Ubuntu 16.04. Why doesn't my virtual Ubuntu machine authenticate with Kerberos, they do have the same IP address but obviously something more is missing. My question is what's missing, and how to fix it?

Answer 1

Kerberos does not work with IP addresses, it relies on domain names and correct DNS entries only. See this marked answer on this topic.

You also can't do Kerberos authentication scenarios with client, server and KDC all running on the same machine . There are known issues with that.
