NAME
pkla-admin-identities - List pklocalauthority-configured polkit
administrators
SYNOPSIS
pkla-admin-identities [--help]
pkla-admin-identities [--config-path config-path]
DESCRIPTION
pkla-admin-identities interprets configuration files described below to
determine which users polkit(8) considers administrators, using a
non-JavaScript configuration file format described below.
Note: Determining which users are considered administrators is driven
by JavaScript rules as described in polkit(8). pkla-admin-identities
is called by a JavaScript rule file named 49-polkit-pkla-compat.rules;
other JavaScript rules with a higher priority may exist, so the
pkla-admin-identities configuration may not necessarily govern the
final decision by polkit(8).
The ordering of the JavaScript rule files and the ordering of
pkla-admin-identities configuration files is not integrated and uses
different rules; the pkla-admin-identities configuration evaluation is
happens at a single point within the JavaScript rule evaluation order.
pkla-admin-identities is an internal helper program of
pkla-polkit-compat. You shouldn't need to run it directly, except for
debugging purposes.
Configuration is read from files with a .conf extension in the
/etc/polkit-1/localauthority.conf.d directory. All files are read in
lexicographical order (using the C locale), meaning that later files
can override earlier ones. The file 50-localauthority.conf contains the
settings provided by the OS vendor. Users and 3rd party packages can
drop configuration files with a priority higher than 60 to change the
defaults. The configuration file format is simple. Each configuration
file is a key file (also commonly known as a ini file) with a single
group called [Configuration]. Only a single key, AdminIdentities is
read. The value of this key is a semi-colon separated list of
identities that can be used when administrator authentication is
required. Users are specified by prefixing the user name with
unix-user:, groups of users are specified by prefixing with
unix-group:, and netgroups of users are specified with unix-netgroup:.
See the section called "EXAMPLE" for an example of a configuration
file.
pkla-admin-identities outputs the resulting configuration of
administrator identities, one identity per line, using the same format
(including e.g. the unix-user: prefix). If no administrator identities
are configured in the above-described configuration files, the output
will be empty.
OPTIONS
-h, --help
Write a summary of the available options to standard output and
exit successfully.
-c, --config-path=config-path
Search for configuration files in config-path instead of the
default /etc/polkit-1/localauthority.conf.d.
EXIT STATUS
pkla-admin-identities exits with 0 on success (even if there are no
administrator identities), and a non-zero status on error.
FILES
/etc/polkit-1/localauthority.conf.d
Default directory containing configuration files.
EXAMPLE
The following .conf file
[Configuration]
AdminIdentities=unix-group:staff
specifies that any user in the staff UNIX group can be used for
authentication when administrator authentication is needed. This file
would typically be installed in the /etc/polkit-1/localauthority.conf.d
directory and given the name 60-desktop-policy.conf to ensure that it
is evaluated after the 50-localauthority.conf file shipped with
pkla-polkit-compat. If the local administrator wants to override this
(suppose 60-desktop-policy.conf was shipped as part of the OS) he can
simply create a file 99-my-admin-configuration.conf with the following
content
[Configuration]
AdminIdentities=unix-user:lisa;unix-user:marge
to specify that only the users lisa and marge can authenticate when
administrator authentication is needed.
