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
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
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 |
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]
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.
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 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.
Initializes the Kerberos database with entries for a new
realm. It’s possible to have more than one realm served by
Reads a previously dumped database, and re-creates that
database from scratch.
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.
