User Configuration GPO doesn't apply to local users

view story

http://serverfault.com – I've modified the Default Domain Policy GPO in a Server 2008 R2 installation and modified some User Configuration policies. On the client machines, I've run gpupdate /force and logged in as a domain user. I can see that the policies are applied fine. When I log in as a local user (admin or non-admin), the user configuration policy isn't applied. rsop.msc and gpresult /R show that no user configuration policies have been applied. The scope of the default domain policy is Authenticated Users. How can I make the user configuration policy apply to local users? (HowTos)
