Just installed a minimal ubuntu 12.04, then installed xfce4 and xinit from the command line after first boot. Totally vanilla installation afaik.

I'm noticing that sudo caches the password until I issue sudo -k to clear it.

This is unexpected behavior in my mind. I've run xfce4 before and don't recall credential caching being on, nor have I experienced it in the many previous ubuntu installs I've had over the years.

Is this a new feature of Ubuntu? Is this something that's the result of the minimal install? Is this an xfce default that's been added recently?

So, I've been playing with asp:PasswordRecovery and discovered I really don't like it, for several reasons: 1) Alice's password can be reset even without having access to Alice's email. A security question for password resets mitigates this, but does not really satisfy me. 2) Alice's new password… >>> More
