Non-Domain user login

Hi Expert,

I created a user to use NAV Password Authentication, then in Navision Server to add this user is a local user, and this user has power user permission .

Now, I used a NB without domain to run Webclient in IE, it’s failed. WebClient show “You are not authorized to sign in,……”. do anybody knows how to let this non-domain user to run Navision.

Thanks
