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 representa-
                 tion in the file filename.

       slave_dump
                 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.

       new_master_key
                 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.

       convert_old_db
                 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.
