- A :class:`LoginDialog` is shown to ask the user for a login,
- if the dialog is canceled, the :class:`AuthError` is re-raised
- otherwise, the function `onAuthEntered` is called.
If the `store login` checkbox in the :class:`LoginDialog` was checked, the information is
set to `self.db.vcs` and :fun:`config.setAuthInformation` is called.
