Authorization via user password breaks after uninstalling then reinstalling ubuntu-desktop

[rusivi2]

1) lsb_release -rd
Description: Ubuntu 10.04.1 LTS
Release: 10.04

2) apt-cache policy ubuntu-desktop
ubuntu-desktop:
  Installed: 1.197
  Candidate: 1.197
  Version table:
 *** 1.197 0
        500 http://us.archive.ubuntu.com/ubuntu/ lucid/main Packages
        100 /var/lib/dpkg/status

3) What I expected to happen is if I uninstalled, then immediately reinstalled ubuntu-desktop, the requirement to type my password to install packages via Synaptic Package Manager or update software via Update Manager would still exist.

4) What happened instead is that after uinstalling, then immediately reinstalling the ubuntu-desktop package, if I install or uninstall a package via Synaptic Package Manager, or update a package via Update Manager, it no longer requires my password.

After about 20 minutes of installing different packages, it is now prompting me again to input my password to access Synaptic. At this point, this bug is considered closed as it seems the functionality was not broken, it just took some time for it to "kick in".

Quick follow-up, I understand the cosmeticality of this issue. However, if someone did the same thing they would come across it. At best, this is a wishlist.
