KADMIND(8) MIT Kerberos KADMIND(8)NAMEkadmind - KADM5 administration server
SYNOPSISkadmind [-x db_args] [-r realm] [-m] [-nofork] [-port port-number] [-P
pid_file] [-p kdb5_util_path] [-K kprop_path] [-F dump_file]
DESCRIPTIONkadmind starts the Kerberos administration server. kadmind typically
runs on the master Kerberos server, which stores the KDC database. If
the KDC database uses the LDAP module, the administration server and
the KDC server need not run on the same machine. kadmind accepts
remote requests from programs such as kadmin(1) and kpasswd(1) to
administer the information in these database.
kadmind requires a number of configuration files to be set up in order
for it to work:
kdc.conf(5)
The KDC configuration file contains configuration information
for the KDC and admin servers. kadmind uses settings in this
file to locate the Kerberos database, and is also affected by
the acl_file, dict_file, kadmind_port, and iprop-related set‐
tings.
kadm5.acl(5)
kadmind's ACL (access control list) tells it which principals
are allowed to perform administration actions. The pathname to
the ACL file can be specified with the acl_file kdc.conf(5)
variable; by default, it is /var/lib/krb5kdc/kadm5.acl.
After the server begins running, it puts itself in the background and
disassociates itself from its controlling terminal.
kadmind can be configured for incremental database propagation. Incre‐
mental propagation allows slave KDC servers to receive principal and
policy updates incrementally instead of receiving full dumps of the
database. This facility can be enabled in the kdc.conf(5) file with
the iprop_enable option. Incremental propagation requires the princi‐
pal kiprop/MASTER\@REALM (where MASTER is the master KDC's canonical
host name, and REALM the realm name) to be registered in the database.
OPTIONS-r realm
specifies the realm that kadmind will serve; if it is not speci‐
fied, the default realm of the host is used.
-m causes the master database password to be fetched from the key‐
board (before the server puts itself in the background, if not
invoked with the -nofork option) rather than from a file on
disk.
-nofork
causes the server to remain in the foreground and remain associ‐
ated to the terminal. In normal operation, you should allow the
server to place itself in the background.
-port port-number
specifies the port on which the administration server listens
for connections. The default port is determined by the kad‐
mind_port configuration variable in kdc.conf(5).
-P pid_file
specifies the file to which the PID of kadmind process should be
written after it starts up. This file can be used to identify
whether kadmind is still running and to allow init scripts to
stop the correct process.
-p kdb5_util_path
specifies the path to the kdb5_util command to use when dumping
the KDB in response to full resync requests when iprop is
enabled.
-K kprop_path
specifies the path to the kprop command to use to send full
dumps to slaves in response to full resync requests.
-F dump_file
specifies the file path to be used for dumping the KDB in
response to full resync requests when iprop is enabled.
-x db_args
specifies database-specific arguments.
Options supported for LDAP database are:
-x nconns=number_of_connections
specifies the number of connections to be maintained
per LDAP server.
-x host=ldapuri
specifies the LDAP server to connect to by URI.
-x binddn=binddn
specifies the DN of the object used by the administra‐
tion server to bind to the LDAP server. This object
should have read and write privileges on the realm
container, the principal container, and the subtree
that is referenced by the realm.
-x bindpwd=bind_password
specifies the password for the above mentioned binddn.
Using this option may expose the password to other
users on the system via the process list; to avoid
this, instead stash the password using the stashsrvpw
command of kdb5_ldap_util(8).
-x debug=level
sets the OpenLDAP client library debug level. level
is an integer to be interpreted by the library.
Debugging messages are printed to standard error, so
this option must be used with the -nofork option to be
useful. New in release 1.12.
