Secure Endpoints has a Heimdal based Hardware Secure KDC product that is
nearing completion.   We presented a talk at the 2009 AFS and Kerberos
Workshop on our model.=20

  http://workshop.openafs.org/afsbpw09/wed_3_3.html

The Heimdal-HSM KDC can run on UNIX platforms as well as Microsoft Window=
s.

If you are interested in pricing and availability, contact me directly.
