Clear SMB network share credentials in OS X

Question

I'm mounting a Windows network share on OS X 10.7 without being asked for the credentials. How can I make OS X forget any stored credential so it asks me?

I've already searched all displayed items in the Keychain, but none looks like it belongs to the Finder.

Answer 1

These are called Network Passwords and don't actually belong to Finder. You'll probably find them in your "login" keychain if you have a closer look (you can also search for the server's name).

_{Never mind that this is a VNC password, it stores them for AFP and SMB as well.}
