43	43	* There is an additional permission management possible on folder level. A folder contains a set of dashboards. A project admin can create folders and manage specific permissions for this folder using Grafana. See this [[link >>https://grafana.com/docs/grafana/latest/dashboards/manage-dashboards/#create-a-dashboard-folder]]for further information. Folder permissions management is out of scope of the user management in the DevOps portal.
44	44	* A project admin is entitled to create and manage "Service Accounts" in Grafana and grant permissions in the specific organization. A Service Account belongs to an Organization (Project) and not to an user. Service Accounts can be used for systems which want to work wit the Grafana API for any automation purposes. See this [[link >>https://grafana.com/docs/grafana/latest/administration/service-accounts/]]for further information. Service Account management is done directly in Grafana and is out of scope of the user management in the DevOps portal.
