+.SH NAME
+kdb_util \-  Kerberos key distribution center database utility
+.SH SYNOPSIS
+kdb_util 
+.B operation filename
+.SH DESCRIPTION
+.I kdb_util
+allows the Kerberos key distribution center (KDC) database administrator to
+perform utility functions on the database.
+.PP
+.I Operation
+must be one of the following:
+.TP 10n
+.I load
+initializes the KDC database with the records described by the
+text contained in the file
+.IR filename .
+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 merge
+merges in the entries from
+.IR filename
+into the database.
+.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
+/kerberos/principal.pag, /kerberos/principal.dir
+DBM files containing database
+.TP
+.IR filename .ok
+semaphore file created by
+.IR slave_dump.
