Following an update to Mountain Lion on my client machine where I have Apple's Remote Desktop running, attempts to control other remote machines still running Lion fail with "authentication failed" errors. The passwords I have for the remote machines are correct, and I can ssh to those machines without issues.

What do I need to do to get Remote Desktop working again? Ideally, this should be something I can do from within Remote Desktop or ssh, as physical access to the remote machines is difficult.

Did you apply the Apple Remote Desktop 3.6 Admin Update? – Mr. Mel Aug 4 '12 at 4:46
@CoconutMan: The Remote Desktop app is version 3.6 (470.93), if that's what you mean. – raxacoricofallapatorius Aug 4 '12 at 4:53
