Grafana Azure AD Integration and mapping CN with Orgs

I was able to integrate my Azure AD authentication with Grafana and could successfully logged in. But now for any user it is being logged into Main Orf (orgd_id = 1). I need to restrict my Azure CN to some other org say with an org_id 32. How can I accomplish this? Is this something configuration with AAD side or in grafana.ini? The documentation does not covering up this.?
