How to assign roles/permissions to users authenticated via ADFS provider?

Hello.
I must import LDAP users, or create them in any other way in Casdoor when I use adfs provider?

no need to import LDAP

adfs provider is just normal oauth provide like github, all you need is to configure the provider info in casdoor

Thank you!

But now I have another question.
i.e. ADFS provider returns code to casdoor after successfull login of a user.
Let's say someone@somedomain.
Casdoor accepts the code and redirects to callback.
How I will assign role/permission to that user if casdoor have no him in his own database?
