listens for requests for changes to the Kerberos database and performs
these, subject to permissions. When starting, if stdin is a socket it
assumes that it has been started by
inetd(8),
otherwise it behaves as a daemon, forking processes for each new
connection. The
--debug
option causes
to accept exactly one connection, which is useful for debugging.
If built with krb4 support, it implements both the Heimdal Kerberos 5
administrative protocol and the Kerberos 4 protocol. Password changes
via the Kerberos 4 protocol are also performed by
kadmind
but the
kpasswdd(8)
daemon is responsible for the Kerberos 5 password changing protocol
(used by
kpasswd(1))
This daemon should only be run on the master server, and not on any
slaves.
Principals are always allowed to change their own password and list
their own principal. Apart from that, doing any operation requires
permission explicitly added in the ACL file
/var/heimdal/kadmind.acl
The format of this file is:
principalrights
[principal-pattern
]
Where rights is any (comma separated) combination of:
change-password or cpw
list
delete
modify
add
get
all
And the optional
principal-pattern
restricts the rights to operations on principals that match the
glob-style pattern.
Supported options:
-c file
--config-file= file
location of config file
-k file
--key-file= file
location of master key file
--keytab= keytab
what keytab to use
-r realm
--realm= realm
realm to use
-d
--debug
enable debugging
-p port
--ports= port
ports to listen to. By default, if run as a daemon, it listens to ports
749, and 751 (if Kerberos 4 support is built and enabled), but you can
add any number of ports with this option. The port string is a
whitespace separated list of port specifications, with the special
string
``+''
representing the default set of ports.
--no-kerberos4
make
ignore Kerberos 4 kadmin requests.

EXAMPLES
This will cause
to listen to port 4711 in addition to any
compiled in defaults:
This acl file will grant Joe all rights, and allow Mallory to view and
add host principals.
