Kerberos is a system for authenticating users and services on a network.
Kerberos is a trusted third-party service. That means that there is a
third party (the Kerberos server) that is trusted by all the entities on
the network (users and services, usually called "principals").
.
This is the MIT reference implementation of Kerberos V5.
.
This package contains a plugin for the TLS functionality used by optional
functionality in MIT Kerberos. The only current consumer is client support
for the MS-KKDCP protocol, which tunnels Kerberos protocol traffic through
an HTTPS proxy.
