Heimdal

The Heimdal KDC also allows administrators to require the use of pre-authentication on a per-principal basis. To require pre-authentication for a principal in the Heimdal KDC database, use the following kadmin command:

kadmin> modify principal
Max ticket life [1 day]:
Max renewable life [1 week]:
Principal expiration time [never]:
Password expiration time [never]:
Attributes []:+requires-pre-auth

The Heimdal KDC also allows you to turn off pre-authentication on all principals when starting the KDC, for emergency or testing purposes. The -p or --no-require-preauth switches disable pre-authentication checks for all principals until the KDC restarts.
