krb5-k5tls 1.17-5 (ppc64el binary) in ubuntu eoan

 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.
