kpasswd - change a user's Kerberos password SYNOPSIS
/usr/bin/kpasswd [principal] DESCRIPTION
The kpasswd command is used to change a Kerberos principal's password. kpasswd prompts for the current Kerberos password, which is used to obtain a changepw ticket from the KDC for the user's Kerberos realm. If kpasswd successfully obtains the changepw ticket, the user is prompted twice for the new password, and the password is changed. If the principal is governed by a policy that specifies the length and/or number of character classes required in the new password, the new password must conform to the policy. (The five character classes are lower case, upper case, numbers, punctuation, and all other charac- ters.) OPERANDS
The following operand is supported: principal Change the password for the Kerberos principal principal. Otherwise, the principal is derived from the identity of the user invoking the kpasswd command. FILES
/tmp/ovsec_adm.xxxxxx Temporary credentials cache for the lifetime of the password changing operation. (xxxxxx is a random string.) ATTRIBUTES

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 per- mission 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: o change-password or cpw o list o delete o modify o add o get o get-keys o 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 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 SEE ALSO
