kadmin -- Kerberos administration utility
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]
The kadmin program is used to make modifications to the Kerberos
database, either remotely via the kadmind(8) daemon, or locally (with the
-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
local admin mode
If no command is given on the command line, kadmin will prompt for
commands 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
add [-r | --random-key] [--random-password] [-p string |
--password=string] [--key=string] [--max-ticket-life=lifetime]
[--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
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
ext_keytab [-k string | --keytab=string] principal...
Creates a keytab with the keys of the specified principals.
Requires get-keys rights.
get [-l | --long] [-s | --short] [-t | --terse] [-o string |
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]
[--expiration-time=time] [--pw-expiration-time=time] [--kvno=number]
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 [--keepold] [-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
Lists the operations you are allowed to perform. These include add,
add_enctype, change-password, delete, del_enctype, get, get-keys,
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 database for strange configurations on important principals.
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 specified
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]
Initializes the Kerberos database with entries for a new realm.
It's possible to have more than one realm served by one server.
Reads a previously dumped database, and re-creates that database
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]
Writes the Kerberos master key to a file used by the KDC.
