From: tytso@MIT.EDU (Theodore Ts'o)
I am proud to announce the release of Kerberos V5 Beta 4. This release
contains several new features, including:
* Configure scripts built from autoconf, to eventually supplant
the imake build system.
* A kadmin server which speaks the Kerberos V4 admin protocol,
but which modifies the V5 database. (For backwards
compatibility; only lightly tested so far.)
* A ksu client.
* Updated GSSAPI code to follow changes in the evolving Internet
* The most recent version of telnet.
* Fixed inter-realm handling so that it actually works
* Updated documentation, including a significantly improved API
* Lots of miscellaneous bug fixes and improvements.
Currently, all of the MIT implementations of the Kerberos protocol are
not fully compliant with the Kerberos RFC. Specifically, we do not
implement the DES w/ MD5 checksum which is required by the RFC; this was
an oversight, where the RFC got updated but the code never did. This
problem still exists in the Beta 4 release, although I expect to have
this fixed in a patch release as soon as possible --- I didn't have time
to have it fixed for this release. I believe that we can fix this with
minimal compatibility impacts with previous versions; vendors
contemplating shipment of this code as product should wait for the patch
release or contact us for futher details.
FTP Instructions: FTP to athena-dist.mit.edu, in /pub/kerberos. Get
the file README.KRB5_BETA4. It will contain instructions on how to
obtain the Beta 4 release.

Appreciation Time!!!! There are far too many people to try to thank
them all; many people have contributed to the development of Kerberos
V5. This is only a partial listing....
Thanks to Mark Eichin at Cygnus for writing the new autoconf
configuration system, for making the code much more portable, and for
serving as pre-release testers.
Thanks to Marc Horowitz, Barry Jaspan, and Jonathan Kamens (and
others) at Openvision, Inc. for providing us with an GSS-API library,
for serving as pre-release testers, and for finding and fixing many
bugs (some of them at the last minute!).
Thanks to Cybersafe (OCSG) for providing patches to fix bugs with
Thanks to Ari Medivnsky and Cliff Neumann for writing a ksu client.
Thanks to Jim Miller from Suite Software for contributing many detailed
bug reports, most of them by doing desk checks over the code!
Thanks to Prasad Upasani from ISI for porting the Berkeley
rlogin/rsh/rcp suite and for testing out our distribution on the Sun.
Thanks to Glenn Machin and Bill Wrahe from Sandia National Labs for
contributing the kadmin server, plus lots of bugfixes.
Thanks to Bill Sommerfeld from HP for commenting on early Kerberos
interface drafts, suggesting improvements in later coding interfaces,
and finding and fixing many bugs.
Thanks to Paul Borman from Cray for writing the Kerberos v4 to v5 glue
layer and the Kerberos v5 subroutines for telnet.
Thanks to Dan Bernstein, for providing the replay cache code.
Thanks to the members of the Kerberos V5 development team at MIT, both
past and present: Jay Berkenbilt, John Carr, Don Davis, Nancy Gilman,
Barry Jaspan, John Kohl, Cliff Neuman, Jon Rochlis, Jeff Schiller, Ted
Ts'o, Tom Yu.
