KADMIN(8)                 BSD System Manager's Manual                KADMIN(8)

NAME
     kadmin -- Kerberos administration utility

SYNOPSIS
     kadmin [-p string | --principal=string] [-K string | --keytab=string]
            [-c file | --config-file=file] [-k file | --key-file=file]
            [-r realm | --realm=realm] [-a host | --admin-server=host]
            [-s port number | --server-port=port number] [-l | --local]
            [-h | --help] [-v | --version] [command]

DESCRIPTION
     The kadmin program is used to make modifications to the Kerberos data-
     base, either remotely via the kadmind(8) daemon, or locally (with the -l
     option).

     Supported options:

     -p string, --principal=string
             principal to authenticate as

     -K string, --keytab=string
             keytab for authentication principal

     -c file, --config-file=file
             location of config file

     -k file, --key-file=file
             location of master key file

     -r realm, --realm=realm
             realm to use

     -a host, --admin-server=host
             server to contact

     -s port number, --server-port=port number
             port to use

     -l, --local
             local admin mode

     If no command is given on the command line, kadmin will prompt for com-
     mands to process. Some of the commands that take one or more principals
     as argument (delete, ext_keytab, get, modify, and passwd) will accept a
     glob style wildcard, and perform the operation on all matching princi-
     pals.

     Commands include:

           add [-r | --random-key] [--random-password] [-p string |
           --password=string] [--key=string] [--max-ticket-life=lifetime]
           [--max-renewable-life=lifetime] [--attributes=attributes]
           [--expiration-time=time] [--pw-expiration-time=time] principal...

                 Adds a new principal to the database. The options not passed
                 on the command line will be promped for.

           add_enctype [-r | --random-key] principal enctypes...

                 Adds a new encryption type to the principal, only random key
                 are supported.

           delete principal...

                 Removes a principal.

           del_enctype principal enctypes...

                 Removes some enctypes from a principal; this can be useful if
                 the service belonging to the principal is known to not handle
                 certain enctypes.

           ext_keytab [-k string | --keytab=string] principal...

                 Creates a keytab with the keys of the specified principals.

           get [-l | --long] [-s | --short] [-t | --terse] [-o string |
           --column-info=string] principal...

                 Lists the matching principals, short prints the result as a
                 table, while long format produces a more verbose output.
                 Which columns to print can be selected with the -o option.
                 The argument is a comma separated list of column names
                 optionally appended with an equal sign (`=') and a column
                 header. Which columns are printed by default differ slightly
                 between short and long output.

                 The default terse output format is similar to -s -o
                 principal=, just printing the names of matched principals.

                 Possible column names include: principal, princ_expire_time,
                 pw_expiration, last_pwd_change, max_life, max_rlife,
                 mod_time, mod_name, attributes, kvno, mkvno, last_success,
                 last_failed, fail_auth_count, policy, and keytypes.

           modify [-a attributes | --attributes=attributes]
           [--max-ticket-life=lifetime] [--max-renewable-life=lifetime]
           [--expiration-time=time] [--pw-expiration-time=time]
           [--kvno=number] principal...

                 Modifies certain attributes of a principal. If run without
                 command line options, you will be prompted. With command line
                 options, it will only change the ones specified.

                 Possible attributes are: new-princ, support-desmd5,
                 pwchange-service, disallow-svr, requires-pw-change,
                 requires-hw-auth, requires-pre-auth, disallow-all-tix,
                 disallow-dup-skey, disallow-proxiable, disallow-renewable,
                 disallow-tgt-based, disallow-forwardable, disallow-postdated

                 Attributes may be negated with a "-", e.g.,

                 kadmin -l modify -a -disallow-proxiable user

           passwd [-r | --random-key] [--random-password] [-p string |
           --password=string] [--key=string] principal...

                 Changes the password of an existing principal.

           password-quality principal password

                 Run the password quality check function locally.  You can run
                 this on the host that is configured to run the kadmind
                 process to verify that your configuration file is correct.
                 The verification is done locally, if kadmin is run in remote
                 mode, no rpc call is done to the server.

           privileges

                 Lists the operations you are allowed to perform. These
                 include add, add_enctype, change-password, delete,
                 del_enctype, get, list, and modify.

           rename from to

                 Renames a principal. This is normally transparent, but since
                 keys are salted with the principal name, they will have a
                 non-standard salt, and clients which are unable to cope with
                 this will fail. Kerberos 4 suffers from this.

           check [realm]

                 Check database for strange configurations on important prin-
                 cipals. If no realm is given, the default realm is used.

     When running in local mode, the following commands can also be used:

           dump [-d | --decrypt] [dump-file]

                 Writes the database in ``human readable'' form to the speci-
                 fied file, or standard out. If the database is encrypted, the
                 dump will also have encrypted keys, unless --decrypt is used.

           init [--realm-max-ticket-life=string]
           [--realm-max-renewable-life=string] realm

                 Initializes the Kerberos database with entries for a new
                 realm. It's possible to have more than one realm served by
                 one server.

           load file

                 Reads a previously dumped database, and re-creates that data-
                 base from scratch.

           merge file

                 Similar to load but just modifies the database with the
                 entries in the dump file.

           stash [-e enctype | --enctype=enctype] [-k keyfile |
           --key-file=keyfile] [--convert-file] [--master-key-fd=fd]

                 Writes the Kerberos master key to a file used by the KDC.
