2.1.2. Service Information 
- If no other parameters are specified when calling the AMO AUTH, the user receives a list of all system AMOs with their corresponding actions.
- It is possible to administer the classes of the AMO actions.
- As a default, a user must have an ID with class of service 10, which is usually the ROOT ID, to change the classes of service.
- Any change to a class affects both AMO languages simultaneously.
- To be able to perform an AMO action, the user must explicitly have the authorization because there is no longer a hierarchy (for example, class 4 does not automatically include classes 1 to 3).
