Hi all, I need to integrate facebook login in a community page. For some reason at the end of the facebook login process I'm still in the middle of my registration process so it means that I need to create a user on community "later" once the user click submit on my community page.

My problem is that SF is expecting to create a new user in the Registration Handler defined in the authentcation provider. There is a way to skip user creation that happens in the implementation of this interface https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_auth_plugin.htm?search_text=Auth.RegistrationHandler or any other best practice to follow?

thanks

Andrea
