PAM module for migrating to MIT Kerberos
A stackable authentication module that takes a username and password from an earlier module in the stack and attempts to transparently add the user to a Kerberos realm using the Kerberos 5 kadmin service. The module can be used to ease the administrative burdens of migrating a large installed userbase from pre-existing authentication methods to a Kerberos-based setup. . This package allows updating the database of a remote MIT Kerberos server.
