OS 10.9 Mavericks keeps prompting to unlock "Local Items" keychain

After migrating a machine to Mavericks, or after binding a Mavericks machine to a new domain, we were getting repeated prompts to unlock the "Local Items" keychain.  No password would unlock the items.

The following steps resolve the problem:

• Go to ~/Library/Keychains (user's Keychain folder)
• Look for a folder that is a long series of numbers and letters: "ADS676BB8-CEJD-45..."
• Delete the folder and IMMEDIATELY restart the Mac

You should no longer be prompted for the Local Items keychain password.

Note: after you restart a new folder with a similar name as the old one (a long series of numbers and letters) will appear in ~/Library/Keychains.  Don't panic, this is normal behaviour.  The new folder corrects the problem.
