KDB_UTIL(8)

NAME
kdb_util - Kerberos key distribution center database utility

SYNOPSIS
kdb_util operation filename

DESCRIPTION
kdb_util allows the Kerberos key distribution center (KDC) database administrator to perform utility functions on the database.

Operation must be one of the following:

load
    initializes the KDC database with the records described by the text contained in the file filename. Any existing database is overwritten.

dump
    dumps the KDC database into a text representation in the file filename.

slave_dump
    performs a database dump like the dump operation, and additionally creates a semaphore file signalling the propagation software that an update is available for distribution to slave KDC databases.

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 filename. The keys in the text representation are encrypted in the new master key.

convert_old_db
    prompts for the master key string, and then dumps the KDC database into a text representation in the file 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).

DIAGNOSTICS

"verify_master_key: Invalid master key, does not match database."
    The master key string entered was incorrect.

FILES

/etc/kerberosIV/principal.db
    DBM file containing database

filename.dump_ok
    semaphore file created by slave_dump.
