Comment 20 for bug 231246

Sorry for the delay - I've been on travel for several weeks and just now am getting back to troubleshooting this.

Per Sebastien Bacher's suggestion:

$ polkit-auth --show-obtainable
<doesn't output anything>

-$ ck-list-sessions
<doesn't output anything>

-$ cat /etc/PolicyKit/PolicyKit.conf
<?xml version="1.0" encoding="UTF-8"?> <!-- -*- XML -*- -->

<!DOCTYPE pkconfig PUBLIC "-//freedesktop//DTD PolicyKit Configuration 1.0//EN"
"http://hal.freedesktop.org/releases/PolicyKit/1.0/config.dtd">

<!-- See the manual page PolicyKit.conf(5) for file format -->

<config version="0.1">
    <match user="root">
        <return result="yes"/>
    </match>
    <define_admin_auth group="admin"/>
</config>
