I wanted to change the name of my printer. As I am always logged in using a non-administrator account I was asked for administrator credentials. I am surprised by this because the text-box fields were not greyed out (example: at the network setting they are greyed out). However I found the following even more curious: my entered admin credentials are remembered. After changing the name or the location of the printer I could change it over and over again without being asked for admin credentials. Can other people confirm this and give their opinion on this.
