I have setup "Remote Management" on a Mac OS X system (running 10.5.8). Trying to connect with a VNC client results in messages like "No supported authentication types" (VineViewer) or "Unknown authType" (Chicken of the VNC).
It's not a firewall issue, since I opened that up. Any suggestions, ideas?
Edit Same issue happens whether I try to connect from the machine itself or from another machine that can ping it.
