Hello -
Trying to complete the challenge where adding Google Social Sign-On to the Partners org.
I believe I've followed the steps, create the Provider, updated the Apex Class from the Git, added to page but when I go to login, receiving, "We can't log you in becasue of the following error. NO_ACCESS: Unable to find a user.
I've created a user with the gmail account I am trying to login with so not sure what else might be causing an issue.
I created a new email account with a completely NEW username (in my case that was a new Gmail username/email) and used this new username when entering a PARTNERS portal with Google. And of course, this user must be with a Partners profile, but you already knew that. :)
I believe the issue is because in the section "Create a Self Registration Page" under the "Register a New Customer" (login page, click on "Not a member?") we had to register a new CUSTOMER and make up a completely new customer and use our email address. In my case, my email address is my USERNAME. And when I tried to log in with Google to PARTNERS portal, naturally I used that same username (because it is the only one I have), and the Partners portal didn't allow me to log in because this username already existed with a previously created customer user created for CUSTOMER portal (Salesforce created that username behind the scene when registering a new customer), and I was getting "NO_ACCESS: User was not authorized for the community".
Hope this was helpful!
