NAME

       kdb5_util - Kerberos Database maintenance utility

SYNOPSIS

       /usr/sbin/kdb5_util [-d dbname] [-f stashfile_name] [-k mkeytype] [-m ] [-M mkeyname] [-P password] [-r realm] cmd

       The kdb5_util utility enables you to create, dump, load, and destroy the Kerberos V5 database. You can also use kdb5_util to create a stash
       file containing the Kerberos database master key.

       The following options are supported:

       -d dbname

           Specify the database name. .db is appended to whatever name is specified. You can specify an absolute path. If you do not  specify  the
           -d option, the default database name is /var/krb5/principal.

       -f stashfile_name

            Specify the stash file name. You can specify an absolute path.

       -k mkeytype

           Specify  the  master  key  type. Valid values are des3-cbc-sha1, des-cbc-crc, des-cbc-md5, des-cbc-raw, arcfour-hmac-md5, arcfour-hmac-
           md5-exp, aes128-cts-hmac-sha1-96, and aes256-cts-hmac-sha1-96.

       -m

           Enter the master key manually.

       -M mkeyname

           Specify the master key name.

       -P password

           Use the specified password instead of the stash file.

       -r realm

           Use realm as the default database realm.

       The following operands are supported:

       cmd      Specifies whether to create, destroy, dump, or load the database, or to create a stash file.

                You can specify the following commands:

                create -s

                    Creates the database specified by the -d option. You will be prompted for the database master password. If you specify  -s,  a
                    stash  file  is  created  as  specified  by  the  -f  option.  If  you  did  not  specify  -f,  the default stash file name is
                    /var/krb5/.k5.realm. If you use the -f, -k, or -M options when you create a database, then you must use the same options  when
                    modifying or destroying the database.

                destroy

                    Destroys the database specified by the -d option.

                stash

                    Creates  a  stash  file. If -f was not specified, the default stash file name is /var/krb5/.k5.realm. You will be prompted for
                    the master database password. This command is useful when you want to generate the stash file from the password.

                dump [-verbose] [filename] [principals]

                    Dumps the Kerberos database to a flat file that can be used for loading or propagating to a slave KDC. See kprop(1M).  Specify
                    file  name  for a location to dump the Kerberos database. If filename is not specified, the principal data is printed to stan-
                    dard error. Specify -verbose to print out the principal names to standard error in addition to being dumping  into  the  file.
                    Use principals to specify the list of principals that should be dumped.

                load [-verbose] [-update] filename

                    Loads  the  database specified by dbname (see -d option, above) with data from the file specified by filename, which must be a
                    file created by the dump command. Use -update to specify that the existing database should be updated; otherwise, a new  data-
                    base is created. Specify -verbose to print out the principal names to standard error, in addition to being loaded.

       Example 1: Creating File that Contains Information about Two Principals

       The following example creates a file named slavedata that contains the information about two principals, jdb@ACME.COM and pak@ACME.COM.

       # /usr/krb5/bin/kdb5_util dump -verbose slavedata
       jdb@ACME.COM pak@ACME.COM

       /var/krb5/principal

           Kerberos principal database.

       /var/krb5/principal.kadm5

           Kerberos administrative database. Contains policy information.

       /var/krb5/principal.kadm5.lock

           Lock file for the Kerberos administrative database. This file works backwards from most other lock files (that is, kadmin exits with an
           error if this file does not exist).

       /var/krb5/principal.ulog

           The update log file for incremental propagation.
