Bug 695372

Description of problem:
The authentication icon(http://www.linuxtopia.org/online_books/redhat_linux_reference_guide/s1-pam-timestamp.html) doesn't always appear in the system tray using Gnome. It depends on the application that first needs root access.
The icon only appears when either the firewall or "Add/Remove Software" is started after entering the root password.
When the Firewall is started, the icon appears but instantly disappears when exiting the firewall configuration window. While the window is still open and key is present, any other program that needs root password will ask for the password.
When "System -> Administration -> Add/Remove Software" is started, the key symbol appears after entering root password. Other programs within the Administration panel can be started without the need to enter the root password again(within timeout), except 'Firewall'.
When any other program from the "Administration" panel is started, no key symbol appears, but all other programs can be started without having to enter root password(again within timeout) except for the firewall.
When starting realcrypt(http://rpmfusion.org/Package/realcrypt), after entering root pw, "Add/Remove Software" can be started without having to enter root password. There doesn't seem to be a timeout for this(after a few hours it still works). The key symbol never appears.


How reproducible:
always

Steps to Reproduce:
(using Gnome Desktop)
e.g
1. start System -> Administration -> Users and Groups
2. enter root password
3. start any other 'Administration' program
  
Actual results:
no key symbol appears

Expected results:
key symbol should be there for all programs enabling elevated privileges
