NAME

       realmd.conf - Tweak behavior of realmd

CONFIGURATION FILE

       realmd can be tweaked by network administrators to act in specific
       ways. This is done by placing settings in a /etc/realmd.conf. This file
       does not exist by default. The syntax of this file is the same as an
       INI file or Desktop Entry file.

       In general, settings in this file only apply at the point of joining a
       domain or realm. Once the realm has been setup the settings have no
       effect. You may choose to configure SSSD[1] or Winbind[2] directly.

       Only specify the settings you wish to override in the /etc/realmd.conf
       file. Settings not specified will be loaded from their packaged
       defaults. Only override the settings below. You may find other settings
       if you look through the realmd source code. However these are not
       guaranteed to remain stable.

       There are various sections in the config file. Some sections are global
       topic sections, and are listed below. Other sections are specific to a
       given realm. These realm specific sections should always contain the
       domain name in lower case as their section header.

       Examples of each setting is found below, including the header of the
       section it should be placed in. However in the resulting file only
       include each section once, and combine the various section setting
       together as lines underneath the section. For example

           [users]
           default-home = /home/%U
           default-shell = /bin/bash

ACTIVE-DIRECTORY

       These options should go in an [active-directory] section of the
       /etc/realmd.conf file. Only specify the settings you wish to override.

       default-client
           Specify the default-client setting in order to control which client
           software is the preferred default for use with Active Directory.

               [active-directory]
               default-client = sssd
               # default-client = winbind

           The default setting for this is sssd which uses SSSD[1] as the
           Active Directory client. You can also specify winbind to use Samba
           Winbind[2].

           Some callers of realmd such as the realm command line tool allow
           specifying which client software should be used. Others, such as
           GNOME Control Center, simplify choose the default.

           You can verify the preferred default client softawre by running the
           following command. The realm with the preferred client software
           will be listed first.

               $ realm discover domain.example.com
               domain.example.com
                 configured: no
                 server-software: active-directory
                 client-software: sssd
                 type: kerberos
                 realm-name: AD.THEWALTER.LAN
                 domain-name: ad.thewalter.lan
               domain.example.com
                 configured: no
                 server-software: active-directory
                 client-software: winbind
                 type: kerberos
                 realm-name: AD.THEWALTER.LAN
                 domain-name: ad.thewalter.lan

       os-name
           (see below)

       os-version
           Specify the os-name and/or os-version settings to control the
           values that are placed in the computer account operatingSystem and
           operatingSystemVersion attributes.

           This is an Active Directory specific option.

               [active-directory]
               os-name = Gentoo Linux
               os-version = 9.9.9.9.9

SERVICE

       These options should go in an [service] section of the /etc/realmd.conf
       file. Only specify the settings you wish to override.

       automatic-install
           Set this to no to disable automatic installation of packages via
           package-kit.

               [service]
               automatic-install = no
               # automatic-install = yes

USERS

       These options should go in an [users] section of the /etc/realmd.conf
       file. Only specify the settings you wish to override.

       default-home
           Specify the default-home setting in order to control how to set the
           home directory for accounts that have no home directory explicitly
           set.

               [users]
               default-home = /home/%D/%U
               # default-home = /nfs/home/%D-%U

           The default setting for this is /home/%D/%U. The %D format is
           replaced by the domain name. The %U format is replaced by the user
           name.

           You can verify the home directory for a user by running the
           following command.

               $ getent passwd 'DOMAIN/User'
               DOMAIN\user:*:13445:13446:Name:/home/DOMAIN/user:/bin/bash
           Note that in the case of IPA domains, most users already have a
           home directory configured in the domain. Therefore this
           configuration setting may rarely show through.

       default-shell
           Specify the default-shell setting in order to control how to set
           the Unix shell for accounts that have no shell explicitly set.

               [users]
               default-shell = /bin/bash
               # default-shell = /bin/sh

           The default setting for this is /bin/bash shell. The shell should
           be a valid shell if you expect the domain users be able to log in.
           For example it should exist in the /etc/shells file.

           You can verify the shell for a user by running the following
           command.

               $ getent passwd 'DOMAIN/User'
               DOMAIN\user:*:13445:13446:Name:/home/DOMAIN/user:/bin/bash
           Note that in the case of IPA domains, most users already have a
           shell configured in the domain. Therefore this configuration
           setting may rarely show through.

REALM SPECIFIC SETTINGS

       These options should go in an section with the same name as the realm
       in the /etc/realmd.conf file. For example for the domain.example.com
       domain the section would be called [domain.example.com]. To figure out
       the canonical name for a realm use the realm command:

           $ realm discover --name DOMAIN.example.com
           domain.example.com
           ...

       Only specify the settings you wish to override.

       computer-ou
           Specify this option to create directory computer accounts in a
           location other than the default. This currently only works with
           Active Directory domains.

               [domain.example.com]
               computer-ou = OU=Linux Computers,DC=domain,DC=example,DC=com
               # computer-ou = OU=Linux Computers,

           Specify the OU as an LDAP DN. It can be relative to the Root DSE,
           or a complete LDAP DN. Obviously the OU must exist in the
           directory.

           It is also possible to use the --computer-ou argument of the realm
           command to create a computer account at a specific OU.

       user-prinicpal
           Set the user-prinicpal to yes to create userPrincipalName
           attributes for the computer account in the realm, in the form
           host/computer@REALM

               [domain.example.com]
               user-principal = yes

       automatic-id-mapping
           This option is on by default for Active Directory realms. Turn it
           off to use UID and GID information stored in the directory (as-per
           RFC2307) rather than automatically generating UID and GID numbers.

           This option only makes sense for Active Directory realms.

               [domain.example.com]
               automatic-id-mapping = no
               # automatic-id-mapping = yes

       manage-system
           This option is on by default. Normally joining a realm affects many
           aspects of the configuration and management of the system. Turning
           this off limits the interaction with the realm or domain to
           authentication and identity.

               [domain.example.com]
               manage-system = no
               # manage-system = yes

           When this option is turned on realmd defaults to using domain
           policy to control who can log into this machine. Further
           adjustments to login policy can be made with the realm permit
           command.

       fully-qualified-names
           This option is on by default. If turned off then realm user and
           group names are not qualified their name. This may cause them to
           conflict with local user and group names.

               [domain.example.com]
               fully-qualified-names = no
               # fully-qualified-names = yes
