Kerberos is a computer-network authentication protocol that works on the basis of tickets to allow nodes communicating over a non-secure network to prove their identity to one another in a secure manner. Kerberos uses UDP port 88 by default
At least two implementations are available, [Heimdal]( https://www.h5l.org/) and (MIT)(https://web.mit.edu/kerberos/).
OpenSSH implements Kerberos support since early versions.
A Kerberos realm is the domain over which a Kerberos authentication server has the authority to authenticate a user, host or service. A realm name is often, but not always the upper case version of the name of the DNS domain over which it presides.
