NAME
kdb_util - Kerberos key distribution center database
utility
SYNOPSIS
kdb_util operation filename
DESCRIPTION
kdbutil 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 representa-
tion in the file filename.
slavedump
performs a database dump like the dump opera-
tion, and additionally creates a semaphore file
signalling the propagation software that an
update is available for distribution to slave
KDC databases.
newmasterkey
prompts for the old and new master key strings,
and then dumps the KDC database into a text rep-
resentation in the file filename. The keys in
the text representation are encrypted in the new
master key.
convertolddb
prompts for the master key string, and then
dumps the KDC database into a text representa-
tion 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.
