Global Operations on the Kerberos Database
The kdb5_util command is the primary tool for administrating the
Kerberos database.  The syntax is:
     kdb5_util command [kdb5_util_options] [command_options]
     
The kdb5_util command takes the following options, which override
the defaults specified in the configuration files:
     
- -r realm
     
- specifies the the Kerberos realm of the database.
     
- -d database_name
     
- specifies the name under which the principal database is stored.
     
- -k master_key_type
     
- specifies the key type of the master key in the database.
     
- -M master_key_name
     
- specifies the principal name of the master key in the database.
     
- -m
     
- indicates that the master database password should be read from the TTY
rather than fetched from a file on disk.
     
- -sf stash_file
     
- specifies the stash file of the master database password
     
- -P password
     
- specifies the master database password.  MIT does not
recommend using this option.
