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.

       merge     merges in the entries  from  filename  into  the
                 database.

       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.
