Any existing database is overwritten. .TP .I dump dumps the KDC database into a text representation in the file .IR filename . .TP .I slave_dump performs a database dump like the .I dump operation, and additionally creates a semaphore file signalling the propagation software that an update is available for distribution to slave KDC databases. .TP .I new_master_key prompts for the old and new master key strings, and then dumps the KDC database into a text representation in the file .IR filename . The keys in the text representation are encrypted in the new master key. .TP .I convert_old_db prompts for the master key string, and then dumps the KDC database into a text representation in the file .IR filename . The existing database is assumed to be encrypted using the old format (encrypted by the key schedule of the master key); the dumped database is encrypted using the new format (encrypted directly with master key). .PP .SH DIAGNOSTICS .TP 20n "verify_master_key: Invalid master key, does not match database." The master key string entered was incorrect. .SH FILES .TP 20n /etc/kerberosIV/principal.db DBM file containing database .TP .IR filename .dump_ok semaphore file created by .IR slave_dump.
