New user being added to all sites

I added a new user to a newly created site within my multi-site environment.

It appears that it was by default added as an admin to all my sites. I then had to go in as Super Admin and remove her from the sites I didn’t want her to have access to.

Is this normal behavior for adding an Admin User to a new site in MU environment ? If so, is there a plugin for that :wink:

What sayeth the group ?
