Hi everyone,
I successfully set up SSO for n8n using Keycloak via OIDC. However, right now any user who has an account in Keycloak can log in to n8n.
Is there a way to restrict which users or groups are allowed to access the n8n instance, while still using SSO with Keycloak?
What is the error message (if any)?
No error — everything works technically, but I need to limit who can log in.
Please share your workflow
