heimdal-kdc 1.2.dfsg.1-5ubuntu1 (i386 binary) in ubuntu karmic

 Heimdal is a free implementation of Kerberos 5 that aims to be
 compatible with MIT Kerberos.
 .
 This package includes the KDC (key distribution center) server,
 which is designed to run on a secure computer and keeps track
 of users' passwords. This is done using the Kerberos protocol in
 such a way that the server computers do not need to know the
 passwords.
