Here’s what docs say:
A nice advantage of allowing your customers to use their own IdP is that they can administer their users and assign roles and access in their own IdP setup instead of forcing you to build administration for them. Working out the mapping for those customers will make this much easier.
But how do they assign roles and permissions defined in my system?
As I understand user must be provisioned to the Auth0 database first (first login), and then organization admin can assign roles to that user.
Am I missing something?
