ICINGA2 & GRAFANA INTEGRATION - Embedded graph Ask for login info

I have switched from IDO db to iginga DB.
After few upfate (grafana modulo in primis)
I have this problem:

The graph is correctly embedded, but ask for login info at first logon.

You can either login from this browser in grafana or allow anonymous visits via

# enable anonymous access
enabled = true

in /etc/grafana/grafana.ini

Is is already enabled.
BUt ask for login the first time…

Additional info…
This is from the ICINGAWEB2 page with GRAFANA login page

SOLVED POPULATING this part of grafana.ini correctly:
