Add/Remove Software error

[Germán A. Racca]

Hi there:

I have a PC with Fedora 12 x86_64 and Gnome desktop, and when I want to
install a program, I go to System -> Administration -> Add/Remove
Software, then I select the package, and finally it asks me for the root
password.

But in my notebook, with Fedora 12 i686 and Gnome desktop, the same
procedure as above doesn't ask me for the root password, but rather I
get the error:

"Authorization failed
You have failed to provide correct authentication
Please check any passwords or account settings."

What happened? I'm missing some configuration steps?

Regards,
Germán
