Keyring and forgotten password

[Francesco Bolzoni]

I forgot the keyring password.
Now, when i try to connect to a windows share, the keyring ask for
password. After a double DENY answer it ask for the share passowrd and i
can login.
I would like to know how delete the keyring or password and create a new
one.

Thanks.
