I'm trying to let members of the group labmembers adjust the CPU frequency scaling on a system using cpufreq-selector. However, by default, this is restricted to members of the admin group.

Per this question, I've created the following file:

/etc/polkit-1/localauthority/30-site.d$ cat 50-cpufreq.pkla 
[CPU Frequency should be allowed for everyone]

However, it seems to have no effect. I can't find any command to reload PolicyKit's configuration, and rebooting doesn't do it either. I've also tried naming it 50-cpufreq.conf, to no more effect. There's nothing I've found that would tell me whether a pkla file is well-formed or anything like that, either.

What am I missing?

It appears that there's a typo in your configuration file. To restrict to a Group (or user) you'll need to use Identity rather than AdminIdentities

From the pklocalauthority man page:

      A semi-colon separated list of globs to match identities. Each glob should start with unix-user: or unix-group: to specify whether to match on a UNIX user name or a UNIX group name.

Ideally the syntax would be:

[CPU Frequency should be allowed for everyone]
