Vista - password manager

Hi,
I'm using Passord Manager (Control Panels/User Accounts/Advanced/Manage
Passwords) as a store for my passwords to remote domains on Windows XP. We
have several Windows domains and they are not trusted. I'm adding my domain
account for all computers in remote domain as one entry for each domain (in
Server : domain\*) as you can see on attached picture.
This solution no longer works in Windows Vista RC1. Every time I tried
adding domain\* entry to Password Manager I have got this response:

Windows cannot save the logon information. Make sure the information is
correct and that all required fields are completed.

Is this new security feature or bug?
