Kerberos provides secure login facilities for Unix, Linux and Windows. Our speaker for this month's Kerberos meeting (and the planned OpenAFS meeting) will be Jeff Altman. Unigroup members will remember that Jeff is a past Unigroup speaker (of Kermit95 and Telnet Security Working Group fame). Jeff has been working with a series of well known security related projects for many years.

MIT Kerberos Version 5 is the basis for the Kerberos distributed with Solaris, AIX, HP-UX, Red Hat Linux, Debian, MacOS X, OpenVMS, and just about every other Kerberos distribution other than the Heimdal distribution and the implementation built into Microsoft Windows 2000 and subsequent releases. MIT is directly responsible for three Kerberos products:

The current releases of MIT Kerberos 5 for Unix/Linux (1.3.3) and KfW (2.6.1) are available from the MIT Kerberos web site:


The MIT Kerberos 5 release 1.3.3 release fixes bugs and adds one major feature:

MIT Kerberos for Windows 2.6 release includes krb5 release 1.3.3 and provides enhanced integration with the Microsoft Windows Kerberos implementation as well as OpenAFS for Windows.

In addition to developing the leading open source implementation of Kerberos, the MIT Kerberos Development Group contributes more than half of the document authors within the IETF Kerberos Working Group. MIT's participation has been crucial to ensuring that all of the major implementations of Kerberos (including Microsoft's) adhere to the published standards to facilitate interoperability.

This talk will provide an introduction to the Kerberos 5 authentication protocol; a detailed overview of the MIT Kerberos implementation; a discussion of interoperability concerns which developers and administrators face when implementing and deploying a multi-platform Kerberos infrastructure; and some demonstrations utilizing the GSS on Linux, Windows, and Java.

Note: If your organization would be interested in providing a grant to further Kerberos development at MIT. Please contact Marshall Vale, Team Leader, of The MIT Kerberos Team, at krbcore@mit.edu.
