It worked for me too!
Sir, God bless you. It worked for me too. Happy new year.
I had the same problem after upgrading to Mavericks. I called up the Apple store, and this was the fix that was given me:
* Go to Finder.
* On the Finder menu, click on "Go", then on "Go to Folder". A box should come up.
* On the box, type in "~/Library/Keychains/" and click on "Go". It should lead you to the Keychains folder where you will find three items: (1) a folder with a name mixed with letters and numbers, (2) login.keychain, and (3) metadata.keychain.
* Delete the folder with a name mixed with letters and numbers.
* Restart your computer. Check to see if the problem has been solved.
It worked for me. Hope it works for you too!
