Heimdal
Just like MIT, Heimdal is also an open source implementation of Kerberos 5. Many Unix distributions have pre-built Heimdal packages, but like MIT, we will cover building Heimdal from source.
Since Heimdal is under development and is distributed from Sweden, it is unencumbered by United States export restrictions and is freely available for download worldwide. Heimdal is a complete clean-room implementation of the Kerberos 5 protocol specification, and as such contains no MIT Kerberos 5 code.
The current version of the Heimdal Kerberos 5 package as of this writing is 0.6. Don’t let the small version number dissuade you from using Heimdal; while it hasn’t been in development quite as long as MIT Kerberos 5, it is feature-complete for the basic Kerberos 5 protocol, and includes as standard features some features that MIT Kerberos doesn’t have, such as incremental database propagation.
Heimdal depends on another package, kth-krb, to enable Kerberos 4 backwards-compatibility. We won’t cover building kth-krb; it has a build process similar to Heimdal, and the only configuration option that you may want to tweak is the prefix directory for the installed binaries and libraries (/usr/athena by default). The source distribution of kth-krb is available from http://www.pdc.kth.se/kth-krb/.
The Heimdal home page is http://www.pdc.kth.se/heimdal/, where you’ll be able to download the latest version of the Heimdal source code.
