Heimdal::Kadm5 is a Perl XS wrapper around the Heimdal Kerberos administrative client library (libkadm5clnt). Heimdal is a free slightly less export challenged implementation of Kerberos5 by Assar Westerlund and Johan Danielsson. This module exposes the API used to administer a Kerberos realm: add, remove, and list principals, create keytabs, change keys, and similar operations.
