Easy Authentication and Authorization in Azure Function App using ARM template

Question

"Easy Authentication and Authorization" feature of Azure App Service works in my Azure Function app if I configure it manually. It does not work when I use an ARM Template.

I used this web site to figure out the config values: https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.management.websites.models.siteauthsettings?view=azuremgmtwebsites-1.6.0-preview

This is what it looks like, ideas?

EDIT : after checking the resulting config at https://resources.azure.com I see that "siteAuthEnabled" and "siteAuthSettings" are not applied at all. Should they be specified somewhere else?
