Project Athena contributed many other pieces of technology to the computing world, including the well-known X Window System.
Kerberos is very different in character and design from SSH; each includes features and services the other lacks.
In this study, we compare the two systems in detail, and then discuss how to combine them to obtain the advantages of both.
If your site already uses Kerberos, you can add SSH while maintaining your existing account base and authentication infrastructure.
This document describes the routines that make up the Kerberos V5 application programming interface.
Version 5 (described in this document) has evolved from Version 4 based on new requirements and desires for features not available in Version 4.The original design and implementation of Kerberos Versions 1 through 4 was the work of Steve Miller of Digital Equipment Corporation and Clifford Neuman (now at the Information Sciences Institute of the University of Southern California), along with Jerome Saltzer, Technical Director of Project Athena, and Jeffrey Schiller, MIT Campus Network Manager.Many other members of Project Athena have also contributed to the work on Kerberos. Nowadays single-sign-on became a hot selling feature for all desktop and web-based products.In this article I talk about single-sign-on implementation in Java platform with Active Directory server.
