Credentials folder and authentification question

Hi,

I'm trying to copy the 'credentials' folder from my Admin account into a user account, but it fails. Once, I log off my admin account (after copying files) and log in into my user account, the content of the credential is empty.

Credentials folder is an encrypted system file that contains all lan passwords and http authentification passwords.

In my user account:
What I want, is open my browser and go, to a secured url with authentification, and when launching the authentification window, my passwords are in (Those passwords, from admin account).
