Hi, I am having trouble authenticating Google users for back office. I have installed the Umbraco Identity Extension Nuget packages from https://github.com/umbraco/UmbracoIdentityExtensions and set everything appropriately.

When I go to the backoffice login page I see the "Log in with google button", however when I click on it it always says access is denied:

I created a new user in backoffice with the gmail username and email address. Is there anything else I have to do to give the google user permission to log into back office? Here is what I'm seeing in fiddler -

I also have this provider settings in my UmbracoSettings.config, is it possible this is causing the problem?

<providers>
<users>
  <!-- if you wish to use your own membershipprovider for authenticating to the umbraco back office -->
  <!-- specify it here (remember to add it to the web.config as well) -->
  <DefaultBackofficeProvider>UsersMembershipProvider</DefaultBackofficeProvider>
</users>

Any help would be appreciated. Thanks!
