don't bug people without admin privileges

[sds]

the user who is not an admin should never be bothered about updates.
when a non-admin user FOO tried to tell update-manager to "never" check for updates,
he is asked for a password for the admin BAR account.
this is absurd!
there is a reason why FOO is not an admin; if he had password for BAR, he would have been an admin himself!
I mark this bug as a security issue because it pushes the users towards the insecure practice of password sharing.

See also bug 876448 which complains about the New Release Available pop-up for non-admins.

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

[sds (sds-gnu)]

this behavior inevitably affects all boxes with non-admin users.
the problem is that non-admin users are unlikely to have a lauchpad account to complain about this.
