I have the following content structure:
|- Home Site1 
|- Home Site2 
|- Shared Content 
|- Media Site1 
|- Media Site2 
|- Shared Media 
And the following configuration:
site_group: ['site', 'site_1', 'site_2']
admin_group: ['admin', 'admin_1', 'admin_2']
site_1_group: ['site_1', 'admin_1']
site_2_group: ['site_2', 'admin_2']
So I have 3 public sites.
Site 1 and Site 2 which are administered by admin_1 and admin 2 respectively.
I also have a global site: Site.
And a global admin BO, which allows me to manage all my sites.
My problem is that my admin_1 is not locked in its root.
I can do the same with both URLs.
