KADMIND(8)

NAME
kadmind - server for administrative access to Kerberos database

SYNOPSIS
kadmind [-c file - -config-file=file] [-k file - -key-file=file] [- -keytab=keytab] [-r realm - -realm=realm] [-d | - -debug] [-p port - -ports=port]

DESCRIPTION
kadmind 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 kadmind to accept exactly one connection, which is useful for debugging.

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:

principal rights [principal-pattern]

Where rights is any (comma separated) combination of:
•   change-password or cpw
•   list
•   delete
•   modify
•   add
•   get
•   get-keys
•   all (everything except get-keys)

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 port 749, 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 port.

FILES
/var/heimdal/kadmind.acl

EXAMPLES
This will cause kadmind to listen to port 4711 in addition to any compiled in defaults:

    kadmind - -ports=+ 4711 &

This acl file will grant Joe all rights, and allow Mallory to view and add host principals, as well as extract host principal keys (e.g., into keytabs).

    joe/admin@EXAMPLE.COM      all
    mallory/admin@EXAMPLE.COM  add,get-keys  host/*@EXAMPLE.COM
