Heimdal Kerberos 5 library

# Introduction

Heimdal libkrb5 library is a implementation of the Kerberos protocol.

Kerberos is a system for authenticating users and services on a network. It is built upon the assumption that the network is `‘unsafe’'. For example, data sent over the network can be eavesdropped and altered, and addresses can also be faked. Therefore they cannot be used for authentication purposes.
