[Observium] Unable to map aut_ldap_groups

Hi,

I´m using the ldap mechanism to auth against our AD. So far I can log in but unable to see any graphs or devices. Apparently the group: $config['auth_ldap_groups']['ObserviumAdmins']['level'] = 10; are not mapped. However, the group "ObserviumAdmins" is present in AD and my username is member of this group. The auth_ldap_groupbase and auth_ldap_group is also correct. Is there anything else I have to take into consideration?
