Configuring Boundary OIDC for Restricted User Authentication

Hi

  • Could you please explain how to restrict the creation of new user accounts in Boundary when authenticating via OIDC, ensuring that only pre-existing users can log in?

  • Alternatively, could you kindly provide guidance on how to configure Boundary to allow login via OIDC only for users who already exist in the Boundary system?

  • Additionally, could you clarify how to permit login via OIDC based on specific criteria, such as allowing only users with certain email addresses (e.g., user1@example.com and user2@example.com) to authenticate and access resources?
