You can add a new attribute "Ragic_User_Name" in SAML Response. By doing so, if the login user account does not exist in Ragic, the system will automatically create a user account and its default email and user name will be the same as SSO's email. Password will be autogenerated as well. It's helpful if your plan is Concurrent Users.
