Hi,
First, I would like to say that everything works fine as expected with the ldap’s authentication and permissions 
Grafana v5.4.3 (6539180) on Ubuntu 16.0.4 LTS
My question is : Grafana permissions works fine with a local account (Internal Authentification), I would like to know if it’s possible to manage the differents permissions even the users authenticated by LDAP only with the Grafana Dashboard of the Server Admin (Manage all users & orgs).
If the group would be managed by this interface and not by the ldap.toml it would be magic !!
Thanks all the team for all your wonderfull work
Mathieu
