An easy question maybe, very new to WPMU

Hello everyone,

I was just wondering how to get the Site Admin menu for new users who registered from parent blog

As when I login as a site admin for new-user.example.com/wp-admin/
I find the following menu is totally missing
Site Admin --> (Missing)
Admin
Blogs
Themes
Options
Admin message (/Missing)

Menu starts from posts, media, links, pages, comments & so on..

Please suggest how to get admin menu for newly registered users..
