Hi cdecanini_,
First of all: Thanks for your reply.
The root-user is the user who was created during installation of the vcloud vm's.
When I try to login to the vcloud-portal (Web interface), I also use the root user.
After login I can see the root-user is already part of the System-Administrator group.
When I use a different organization, "dev" or "catalog" for example and use another
user with the role "organization admin" this is also not working.
Very strange to me ...
greetz,
Steven
