Comment 18 for bug 326135

>Since these unix groups seems to be abandoned, the right solution I think is to remove that settings page.

Perhaps. That would take the bug away, but it wouldn't implement the missing feature. (Being able to create Desktop users who cannot tell the computer to make wireless or modem connections).

>Users that have advanced needs (don't run desktop for example), can still happily use these settings.

I'd be happy to do this manually but I don't know how (not that this is the place for you to tell me...)
