Disk utility asks for password for authopen when creating images

Question

I just upgraded to Mountain Lion from Lion 10.7.4.
Now, whenever I use disk utility to create a image from a CD/DVD, I get a dialog window saying that :
authopen is trying to open the chosen file.
Type your password to allow this.
I never saw this dialog in Lion. Why am I getting this message?
Also, after upgrading to ML I cannot eject the CD/DVD after my cdr or dmg file is created. I have to wait a few minutes. In Lion I only had to wait a few seconds.
I tried the usual permissions repair, reboot, etc.
*By the way I have been using Macs since the good old days of G3, before the iPod was invented, so I am not totally clueless here. My forum ID got messged up so I had to create a new Apple ID.

To get around this issue, the group name needs to be changed to 'everyone' in the sys.openfile section of /etc/authorization. You will still need to authenticate, but you do not need to have admin credentials:
