[ovirt-users] Grafana login

Hi! I have installed oVirt 4.5.1 and I am using KeyCloak to login. I have created users in keycloak and with them i can login to ovirt Manager, but I can't login to Grafana. Also, I can login to Keycloak only with user "admin" and not with newly created users. I have tried to add @ovirt or @ovirt@internal, but every time i get "Invalid username or password" I haven't really changed default options in keycloak and can't find good manual for ovirt + keyclock. Can anyone tell me how to create user in keycloak that cant login to Grafana? Regards,
