Scope Manage an enterprise

Hello,

I want to login to my account (vusing the API) using scopes.

When I try to login whithout scopes (line beelow) there is no problem.

https://account.box.com/api/oauth2/authorize?response_type=code&client_id=&redirect_uri=&state=

 But when I try to login using the manage_enterprise scope (by adding "&scope=manage_enterprise") I get this error : error=invalid_scope&error_description=Unsupported+scope+was+requested.

It seems that the only scope which is working is root_readwrite..

Can someone help me ?

Thanks in advance,

Thomas
