[Bug 1008344] Re: checks "admin" group membership instead of querying polkit

[Nikki VonHollen]

philw85: I completely agree. The time settings dialog is a great example
for how this should work.

I think it's also fine to just let PolicyKit prompt when it needs to
without telling the user beforehand. Average Ubuntu users are going to
be admins on their single-user systems, and where users are not admins
on their own machines it will still be clear what the problem is.

Dialogs that connect to services that use PolicyKit don't need to be
aware PolicyKit exists, and keeping those dialogs unaware of PolicyKit
makes them flexible for more exotic configurations. There are so many
in-the-middle configurations where the user is almost an admin, but
can't do absolutely everything. Maybe the user is configured to be able
to change time/language settings and install trusted packages, but isn't
allowed to install untrusted packages. My point is that the question "is
the user an admin?" is very ambiguous, so it's better to just not ask
and let PolicyKit handle it.

Title:
  checks "admin" group membership instead of querying polkit

Status in “language-selector” package in Ubuntu:
  Triaged

Bug description:
  In a new install of Ubuntu Precise, I cannot make any system-wide
  changes in the language selector (such as installing languages or
  clicking "Apply System-Wide"), only user-specific changes. All those
  controls for system-wide changes are greyed out, although my user does
  have sudo abilities and I would be able to enter the root password of
  the machine.

  The machine is freshly installed, but with customizations specific to
  our site, e.g. ldap authentication for users. Specifically, my user is
  an ldap user, not a local one, and there is a group in the ldap
  directory which was granted sudo capability by adding it to
  /etc/sudoers. My user is part of that group. sudo on the command line
  and gksudo work fine.
