Polkit-0.111

Introduction to Polkit

Polkit is a toolkit for defining and handling authorizations. It is used for allowing unprivileged processes to communicate with privileged processes.

This package is known to build and work properly using an LFS-7.4 platform.

If libxslt-1.1.28 is installed, then docbook-xml-4.5 and docbook-xsl-1.78.1 are required. If you have installed libxslt-1.1.28, but you do not want to install any of the DocBook packages mentioned, you will need to use --disable-man-pages in the instructions below.

User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/polkit

Installation of Polkit

There should be a dedicated user and group to take control of the polkitd daemon after it is started. Issue the following commands as the root user:

groupadd -fg 27 polkitd &&
useradd -c "PolicyKit Daemon Owner" -d /etc/polkit-1 -u 27 \
        -g polkitd -s /bin/false polkitd

Install Polkit by running the following commands:


./configure --prefix=/usr        \
            --sysconfdir=/etc    \
            --localstatedir=/var \
            --with-authfw=shadow \
            --disable-static     \
            --libexecdir=/usr/lib/polkit-1 &&

make

To test the results, issue: make check. Note that system D-Bus daemon must be running for the testsuite to complete. There is also a warning about ConsoleKit database not present, but that one can be safely ignored.

Now, as the root user:

make install

Command Explanations

--with-authfw=shadow: This parameter configures the package to use the Shadow rather than the Linux PAM Authentication framework. Remove it if you would like to use Linux PAM.

--disable-static: This switch prevents installation of static versions of the libraries.

--enable-gtk-doc: Use this parameter if GTK-Doc is installed and you wish to rebuild and install the API documentation.

Configuring Polkit

PAM Configuration

[Note]

Note

If you did not build Polkit with Linux PAM support, you can skip this section.

If you have built Polkit with Linux PAM support, you need to modify the default PAM configuration file which was installed by default to get Polkit to work correctly with BLFS. Issue the following commands as the root user to create the configuration file for Linux PAM:

cat > /etc/pam.d/polkit-1 << "EOF"
# Begin /etc/pam.d/polkit-1

auth     include        system-auth
account  include        system-account
password include        system-password
session  include        system-session

# End /etc/pam.d/polkit-1
EOF
