VMC USers and Groups - add user greyed out

I'm logged on as cloudadmin. When I go under users and groups the add user is grayed out when I select vmc.local or mydomain.com.

Also, when I look at groups it says You have no privileges to view this object or it does not exist.

I can't add a mydomain\user-group to the global permissions.

Any suggestions. This is a brand new environment running in HLM mode.
