@heading What is Heimdal?

Heimdal is a free implementation of Kerberos 5. The goals are to:

@itemize @bullet
@item
have an implementation that can be freely used by anyone
@item
be protocol compatible with existing implementations and, if not in
conflict, with RFC 4120 (and any future updated RFC). RFC 4120
replaced RFC 1510.
@item
be reasonably compatible with the M.I.T Kerberos V5 API
@item
have support for Kerberos V5 over GSS-API (RFC1964)
@item
include the most important and useful application programs (rsh, telnet,
popper, etc.)
@item
include enough backwards compatibility with Kerberos V4
@end itemize

@heading Status

Heimdal has the following features (this does not mean any of this
works):

@itemize @bullet
@item
a stub generator and a library to encode/decode/whatever ASN.1/DER
stuff
@item
a @code{libkrb5} library that should be possible to get to work with
simple applications
@item
a GSS-API library
@item
@file{kinit}, @file{klist}, @file{kdestroy}
@item
@file{telnet}, @file{telnetd}
@item
@file{rsh}, @file{rshd}
@item
@file{popper}, @file{push} (a movemail equivalent)
@item
@file{ftp}, and @file{ftpd}
@item
a library @file{libkafs} for authenticating to AFS and a program
@file{afslog} that uses it
@item
some simple test programs
@item
a KDC that supports most things; optionally, it may also support
Kerberos V4 and kaserver,
@item
simple programs for distributing databases between a KDC master and
slaves
@item
a password changing daemon @file{kpasswdd}, library functions for
changing passwords and a simple client
@item
some kind of administration system
@item
Kerberos V4 support in many of the applications.
@end itemize
