Raging through the tech blogs Thursday was a Groklaw report that Microsoft seemingly has sneakily patented an open-source technology called "sudo."

Sudo (pronounced SOO-doo) is a computer command that allows a system user to input an administrative password to do a task, such as installing an application, the user doesn't normally have permission to do. It's an important part of Linux operating systems and Apple's Mac OSX.

The answer, it seems, is a resounding no. "I really don't think that that patent applies to sudo. I read through it and it seems to be something completely different," said Todd Miller, the engineer who has managed and developed sudo since 1993. "That would be the answer I would say: 'No.'"
