Restricted permission for admin users

Hi

We have a problem with the wp-admin access in our multisite network. When a new person set up an user it works fine, but when the user presses his username in the right corner, it navigates the user to a page he does not have access to. It says "Du har ikke tilstrækkelige rettigheder til at se denne side." which translates to: you do not have the neccesary permission for this page.
