Multi organization LDAP

I have created a second organization but I cannot see any LDAP users I have previously created.
I tried in ldap.toml to add a new servers.group_mappings with :
org_role = “Viewer”
Then I added a LDAP user to this new_group (created in LDAP).
But it does not work. Could you help me on this subject (grafana 5.4.3) ?

Oups Sorry : it works I have made a mistake in the group name.

An other question : is is possible to put multiple org_id in the same servers.group_mappings ?
