Problem with "Enter password to unlock your login keyring"
I'm using Ubuntu 10.04LTS.
I'm trying to configure my chat accounts.
But after entering username and password, it is asking "Enter password to unlock your login keyring".
I have entered my login password. But it is saying that "The password you use to log in to your computer no longer matches that of your login keyring."
What is this password and how to resolve this?
