Hi Jens,

You configured permissions to edit CIB. But it is also required to 
assign permissions to use pcsd (only root is allowed to start and stop 
services, so the request goes through pcsd).

This can be done using pcs web UI:
- open the web UI in your browser at https://<your node address>:2224
- login as hacluster user
- add existing cluster
- go to permissions
- set permissions for your cluster
- don't forget to apply changes

Regards,
Tomas
